     TECHNICAL FIELD 
     The present invention relates generally to wireless communication devices, and more particularly to a graphical user interface for controlling such devices. 
     DESCRIPTION OF THE RELATED ART 
     With the proliferation of communications services available on wireless mobile devices, it becomes increasingly complex to create a single device that can excel at many different functions. Many critics claim that a wireless telephone device can never make a good handheld personal digital assistant (PDA) device and a handheld PDA device will never make a good wireless telephone. It is also said that only teenagers are using Instant Messaging (IM) services or Short Message Services (SMS) to exchange messages with friends and acquaintances and that such users should get an entirely different wireless mobile device. However, many users of wireless handheld devices desire to have multiple services and functionality on a single device. 
     Representing multiple services and functions to a user on a single wireless mobile device presents a number of challenges to the designer of a user interface, particularly a graphical user interface (GUI), for controlling the device. Wireless devices are usually small relative to less portable computing devices such as laptops and desktop computers. Inherently then, a visual display such as an LCD or other screen component of the wireless mobile device has a small display area. 
     Typically, GUIs for wireless mobile devices comprise a main or home screen and one or more sub-screens that may be navigated from the main screen. Notification icons are often rendered on a portion of the main screen to indicate a new event such as the receipt of a new IM message, electronic mail (e-mail) or other service event such as a calendar reminder or alarm and other status information such as time, date and battery life. For each type of service or function available via the device, a graphical image or icon is often rendered on a major portion of the main screen, which icon may be selected using a cursor or other means to launch a specific GUI for the selected service or function. 
     A user may subscribe to multiple similar services and have these services available via a single wireless mobile device. For example, a user may subscribe to more than one Instant Message-type service, such as AOL™ Instant Messenger (AIM™), ICQ™, Microsoft Network™ (MSN™), Yahoo!™ Messenger and Quick Messaging™. Alternatively or as well, a user may have a corporate and personal e-mail account coupled to the wireless mobile device. When a user is notified of a new event such as a new IM message, the user is required to check each of their IM service applications separately, via their respective activation icons, to determine which IM service is responsible for the new event. Checking each service is inconvenient. Moreover, there is a demand to have information made available to a user quicker than previously available in order to optimize the control of the wireless device. 
     Accordingly, there is a resulting need for a method and apparatus that addresses one or more of these shortcomings.

     DETAILED DESCRIPTION 
     The invention relates to a method, graphical user interface and apparatus for notifying and previewing a new event on a display of a device. 
     In accordance with a first aspect of the invention, there is provided a method for a computing device having a plurality of applications for managing respective events, individual ones of said applications each represented by an application icon on a screen of a graphical user interface for the device. The method for previewing new events on the screen comprises, in response to a new event of a one of said applications, visually modifying the one of said applications&#39; icon to notify of the new event. In response to the visually modified icon, a user may invoke the one of said applications. 
     The one of said applications may be monitored to determine an occurrence of the new event. Further, the first aspect may comprise determining a visual modification for the one of said applications&#39; icon in response to the new event; and using said visual modification when visually modifying. Determining a visual modification may comprise maintaining a count of new events for the one of said applications and visually modifying the one of said applications&#39; icon may comprise displaying a preview of a content of the new event. Displaying a preview can be responsive to a user action, such as an interaction with the modified icon. Displaying a preview of a content can comprise displaying a dialog box over a portion of the main screen. 
     In one embodiment, the method comprises, in response to an activation of the one of said applications having its icon visually modified to notify of the new event, automatically navigating through the one of said applications to the new event. 
     In one embodiment, the device comprises at least one of a data communication device and a voice communication device and at least some of said plurality of applications manage communications capabilities associated with the device. As such, the events of said at least some of said plurality of applications comprise communication events. For example, the device may be a wireless device. 
     In a second aspect, in a computing device having a controller coupled to a memory, the memory storing a plurality of applications for managing respective events, there is provided a graphical user interface (GUI) for the applications. The GUI comprises a main screen for displaying on the computing device, the screen comprising a plurality of icons, each icon associated with one of the plurality of applications; at least one monitoring component to determine the occurrence of new events of the applications; and at least one icon modifying component to modify a one of the icons for display on the main screen in response to a new event of the application associated with the one of the icons to notify of the new event. 
     In a third aspect there is provided a wireless handheld device comprising a controller; a memory coupled to the controller, the memory storing a plurality of applications for execution by the controller to manage respective events and a graphical user interface (GUI) for the applications. The GUI comprises a main screen for displaying on the device, the screen comprising a plurality of icons, each icon associated with one of the plurality of applications; at least one monitoring component to determine the occurrence of new events of the applications; and at least one icon modifying component to modify a one of the icons for display on the main screen in response to a new event of the application associated with the one of the icons to notify of the new event. 
     Method and apparatus for previewing new events in a computing device having a plurality of applications for managing respective events are described. Individual applications are each represented by an application icon on a screen of a graphical user interface for the device. When a new event occurs, particularly when the new event relates to a specific one of a plurality of similar applications, the invention provides a convenient way to denote which application relates to the event. In response to a new event of a one of the applications, the application&#39;s icon is visually modified to notify of the new event. A visual modification may be determined in response to the new event, for example, to preview a content of the event. The visual modification may include a count of all new events that remain to be disposed. On a selection of the visually modified icon, additional previewing may be provided. Activation of the application having a visually modified application icon may be configured to automatically initiate the application at the new event. 
       FIG. 1  is a block diagram of a communication system  100  which includes a mobile station  102  which communicates through a wireless communication network  104  symbolized by a station. Mobile station  102  preferably includes a visual display  112 , a keyboard  114 , and perhaps one or more auxiliary user interfaces (UI)  116 , each of which are coupled to a controller  106 . Controller  106  is also coupled to radio frequency (RF) transceiver circuitry  108  and an antenna  110 . 
     Typically, controller  106  is embodied as a central processing unit (CPU) which runs operating system software in a memory component (not shown). Controller  106  will normally control overall operation of mobile station  102 , whereas signal processing operations associated with communication functions are typically performed in RF transceiver circuitry  108 . Controller  106  interfaces with device display  112  to display received information, stored information, user inputs, and the like. Keyboard  114 , which may be a telephone type keypad or full alphanumeric keyboard, is normally provided for entering data for storage in mobile station  102 , information for transmission to network  104 , a telephone number to place a telephone call, commands to be executed on mobile station  102 , and possibly other or different user inputs. 
     Mobile station  102  sends communication signals to and receives communication signals from the wireless network  104  over a wireless link via antenna  110 . RF transceiver circuitry  108  performs functions similar to those of a base station and a base station controller (BSC) (not shown), including for example modulation/demodulation and possibly encoding/decoding and encryption/decryption. It is also contemplated that RF transceiver circuitry  108  may perform certain functions in addition to those performed by a BSC. It will be apparent to those skilled in art that RF transceiver circuitry  108  will be adapted to particular wireless network or networks in which mobile station  102  is intended to operate. 
     Mobile station  102  includes a battery interface (IF)  134  for receiving one or more rechargeable batteries  132 . Battery  132  provides electrical power to electrical circuitry in mobile station  102 , and battery IF  132  provides for a mechanical and electrical connection for battery  132 . Battery IF  132  is coupled to a regulator  136  which regulates power to the device. When mobile station  102  is fully operational, an RF transmitter of RF transceiver circuitry  108  is turned on only when it is sending to network, and is otherwise turned off or placed in a low-power mode to conserve power. Similarly, an RF receiver of RF transceiver circuitry  108  is typically periodically turned off to conserve power until it is needed to receive signals or information (if at all) during designated time periods. 
     Mobile station  102  operates using a Subscriber Identity Module (SIM)  140  which is connected to or inserted in mobile station  102  at a SIM interface (IF)  142 . SIM  140  is one type of a conventional “smart card” used to identify an end user (or subscriber) of mobile station  102  and to personalize the device, among other things. Without SIM  140 , the mobile station terminal is not fully operational for communication through the wireless network. By inserting SIM  140  into mobile station  102 , an end user can have access to any and all of his/her subscribed services. SIM  140  generally includes a processor and memory for storing information. Since SIM  140  is coupled to SIM IF  142 , it is coupled to controller  106  through communication lines  144 . In order to identify the subscriber, SIM  140  contains some user parameters such as an International Mobile Subscriber Identity (IMSI). An advantage of using SIM  140  is that end users are not necessarily bound by any single physical mobile station. SIM  140  may store additional user information for the mobile station as well, including datebook (or calendar) information and recent call information. 
     Mobile station  102  may consist of a single unit, such as a data communication device, a multiple-function communication device with data and voice communication capabilities, a personal digital assistant (PDA) enabled for wireless communication, or a computer incorporating an internal modem. Alternatively, mobile station  102  may be a multiple-module unit comprising a plurality of separate components, including but in no way limited to a computer or other device connected to a wireless modem. In particular, for example, in the mobile station block diagram of  FIG. 1 , RF transceiver circuitry  108  and antenna  110  may be implemented as a radio modem unit that may be inserted into a port on a laptop computer. In this case, the laptop computer would include display  112 , keyboard  114 , one or more auxiliary UIs  116 , and controller  106  embodied as the computer&#39;s CPU. It is also contemplated that a computer or other equipment not normally capable of wireless communication may be adapted to connect to and effectively assume control of RF transceiver circuitry  108  and antenna  110  of a single-unit device such as one of those described above. Such a mobile station  102  may have a more particular implementation as described later in relation to mobile station  202  of  FIG. 2 . 
       FIG. 2  is a detailed block diagram of a preferred mobile station  202 . Mobile station  202  is preferably a two-way communication device having at least voice and advanced data communication capabilities, including the capability to communicate with other computer systems. Depending on the functionality provided by mobile station  202 , it may be referred to as a data messaging device, a two-way pager, a cellular telephone with data messaging capabilities, a wireless 
     Internet appliance, or a data communication device (with or without telephony capabilities). Mobile station  202  may communicate with any one of a plurality of fixed transceiver stations  200  within its geographic coverage area. 
     Mobile station  202  will normally incorporate a communication subsystem  211 , which includes a receiver, a transmitter, and associated components, such as one or more (preferably embedded or internal) antenna elements and, local oscillators (LOs), and a processing module such as a digital signal processor (DSP) (all not shown). Communication subsystem  211  is analogous to RF transceiver circuitry  108  and antenna  110  shown in  FIG. 1 . As will be apparent to those skilled in field of communications, particular design of communication subsystem  211  depends on the communication network in which mobile station  202  is intended to operate. 
     Network access is associated with a subscriber or user of mobile station  202  and therefore mobile station  202  requires a Subscriber Identity Module or “SIM” card  262  to be inserted in a SIM IF  264  in order to operate in the network. SIM  262  includes those features described in relation to  FIG. 1 . Mobile station  202  is a battery-powered device so it also includes a battery IF  254  for receiving one or more rechargeable batteries  256 . Such a battery  256  provides electrical power to most if not all electrical circuitry in mobile station  202 , and battery IF  254  provides for a mechanical and electrical connection for it. The battery IF  254  is coupled to a regulator (not shown) which provides power V+to all of the circuitry. 
     Mobile station  202  includes a microprocessor  238  (which is one implementation of controller  106  of  FIG. 1 ) which controls overall operation of mobile station  202 . Communication functions, including at least data and voice communications, are performed through communication subsystem  211 . Microprocessor  238  also interacts with additional device subsystems such as a display  222 , a flash memory  224 , a random access memory (RAM)  226 , auxiliary input/output (I/O) subsystems  228 , a serial port  230 , a keyboard  232 , a speaker  234 , a microphone  236 , a short-range communications subsystem  240 , and any other device subsystems generally designated at  242 . Some of the subsystems shown in  FIG. 2  perform communication-related functions, whereas other subsystems may provide “resident” or on-device functions. Notably, some subsystems, such as keyboard  232  and display  222 , for example, may be used for both communication-related functions, such as entering a text message for transmission over a communication network, and device-resident functions such as a calculator or task list. Operating system software used by microprocessor  238  is preferably stored in a persistent store such as flash memory  224 , which may alternatively be a read-only memory (ROM) or similar storage element (not shown). Those skilled in the art will appreciate that the operating system, specific device applications, or parts thereof, may be temporarily loaded into a volatile store such as RAM  226 . 
     Microprocessor  238 , in addition to its operating system functions, preferably enables execution of software applications on mobile station  202 . A predetermined set of applications which control basic device operations, including at least data and voice communication applications, will normally be installed on mobile station  202  during its manufacture. A preferred application that may be loaded onto mobile station  202  may be a personal information manager (PIM) application having the ability to organize and manage data items relating to the user such as, but not limited to, instant messaging (IM), e-mail, calendar events, voice mails, appointments, and task items. Naturally, one or more memory stores are available on mobile station  202  and SIM  262  to facilitate storage of PIM data items and other information. 
     The PIM application preferably has the ability to send and receive data items via the wireless network. In a preferred embodiment, PIM data items are seamlessly integrated, synchronized, and updated via the wireless network, with the mobile station user&#39;s corresponding data items stored and/or associated with a host computer system thereby creating a mirrored host computer on mobile station  202  with respect to such items. This is especially advantageous where the host computer system is the mobile station user&#39;s office computer system. Additional applications may also be loaded onto mobile station  202  through network  200 , an auxiliary I/O subsystem  228 , serial port  230 , short-range communications subsystem  240 , or any other suitable subsystem  242 , and installed by a user in RAM  226  or preferably a non-volatile store (not shown) for execution by microprocessor  238 . Such flexibility in application installation increases the functionality of mobile station  202  and may provide enhanced on-device functions, communication-related functions, or both. For example, secure communication applications may enable electronic commerce functions and other such financial transactions to be performed using mobile station  202 . 
     In a data communication mode, a received signal such as a text message, an e-mail message, or web page download will be processed by communication subsystem  211  and input to microprocessor  238 . Microprocessor  238  will preferably further process the signal for output to display  222 , to auxiliary I/O device  228  or both as described further herein below with reference to  FIGS. 3-9 . A user of mobile station  202  may also compose data items, such as e-mail messages, for example, using keyboard  232  in conjunction with display  222  and possibly auxiliary I/O device  228 . Keyboard  232  is preferably a complete alphanumeric keyboard and/or telephone-type keypad. These composed items may be transmitted over a communication network through communication subsystem  211 . 
     For voice communications, the overall operation of mobile station  202  is substantially similar, except that the received signals would be output to speaker  234  and signals for transmission would be generated by microphone  236 . Alternative voice or audio I/O subsystems, such as a voice message recording subsystem, may also be implemented on mobile station  202 . Although voice or audio signal output is preferably accomplished primarily through speaker  234 , display  222  may also be used to provide an indication of the identity of a calling party, duration of a voice call, or other voice call related information, as some examples. 
     Serial port  230  in  FIG. 2  is normally implemented in a personal digital assistant (PDA)-type communication device for which synchronization with a user&#39;s desktop computer is a desirable, albeit optional, component. Serial port  230  enables a user to set preferences through an external device or software application and extends the capabilities of mobile station  202  by providing for information or software downloads to mobile station  202  other than through a wireless communication network. The alternate download path may, for example, be used to load an encryption key onto mobile station  202  through a direct and thus reliable and trusted connection to thereby provide secure device communication. 
     Short-range communications subsystem  240  of  FIG. 2  is an additional optional component which provides for communication between mobile station  202  and different systems or devices, which need not necessarily be similar devices. For example, subsystem  240  may include an infrared device and associated circuits and components, or a Bluetooth™ communication module to provide for communication with similarly-enabled systems and devices. Bluetooth™ is a registered trademark of Bluetooth SIG, Inc. 
     In accordance with an embodiment of the invention, mobile station  202  is configured for sending and receiving data items and includes a PIM for organizing and managing data items relating to the user such as, but not limited to, instant messaging (IM), e-mail, calendar events, calendar appointments, and task items, etc. By way of example, mobile station  202  is configured for three instant messaging services and two e-mail services to which the user subscribes. To provide a user-friendly environment to control the operation of mobile station  202 , PIM together with the operation system and various software applications resident on the station  202  provides a GUI having a main screen and a plurality of sub-screens navigable from the main screen. 
     Referring now to  FIG. 3 , there is an illustration of an exemplary main screen  300 , in accordance with an embodiment of the invention, for display  222  of mobile station  202  providing a graphical user interface for controlling mobile station  202 . Main screen  300  is divided into two main portions, namely an application portion  301  for displaying and manipulating icons (e.g.  304 - 312 ) for various software applications and functions enabled by mobile station  202  and a mobile station status portion  302  for displaying status information such as time, date, battery and signal strength, etc.  FIG. 3  illustrates three icons  304 ,  306  and  308  for respective IM applications IM  1 , IM  2  and IM  3  and two icons  310 ,  312  for the two e-mail services Email  1  and Email  2 . Associated with each icon is a name (e.g. IM  1 ) for the application for icon  304 . The name may also be presented in a name region  314  of application portion  301 . 
     Main screen  300  may not represent all application icons at once in application portion  301 . A user may be required to navigate or scroll through the icons of application portion  301  to view additional application icons. 
     For simplicity, each icon is represented as a circle but persons of ordinary skill in the art will appreciate that other graphics may be used. In the exemplary main screen and GUI of mobile station  202 , when a particular icon, e.g.  304 , is selected or made active by a user (such as by manipulating keyboard  232  or other auxiliary I/O device  228 ), the icon  304  is changed such as by highlighting, shadowing or the like. 
     In accordance with an embodiment of the invention, an icon (e.g.  304 ) may be visually modified in response to a new event from the application associated with the icon to provide an immediate notification of the event via a change in main screen  300 . The notification may distinguish the icon from icons for similar services to assist a user to control mobile station  202  as described further. 
     Each of the icons in the main screen  300  of  FIG. 3  is in an initial state indicating no new events have occurred and remain unattended by the user.  FIG. 4  is an illustration of the main screen  300  after a new IM event, for example, a new message, has arrived into one of the IM applications, namely IM  2 , associated with icon  306 . In this exemplary embodiment, the new IM message is indicated with a visual modification  400  comprising a bubble, alluding to new received text, and a numeric indicator “1” representing a count of new events, which in this case are unread messages. Persons of ordinary skill in the art will appreciate that a visual modification  400  different from a bubble may be used and the count may represent other information, such as the number of correspondents or “buddies” from which one or more messages have been received but remain unread. In addition to indicating the number of unread messages, this mechanism may be used to reflect other new event information such as additional state information pertaining to the associated application. State information may include whether the user is currently signed in (and their user name), the state of the connection, and the current state of the user (away vs. available). In an e-mail application, such as associated with one of icons  310 ,  312 , a count may be of unread e-mail messages or distinct senders of unread e-mail. Similar counts may represent SMS messages, appointments, alarms or other events for respective applications. 
     Optionally, the count may be configurable for each application or instance thereof. For application icon  304  it may identify the number of distinct senders of unread IM messages and for application icon  308  distinct unread IM messages. 
       FIG. 5  is an illustration of IM application icon  306  following a user action. When the user of mobile station  202  moves the focus of main screen from icon  304  through  306  and  308  to highlight phone icon  502 , visual modification  400  persists at icon  306  to maintain the visual modification and remind the user of the unread message. Preferably, only once the user activates an application and reads the unread message is the visual modification changed, for example, to decrease the count and, if applicable, remove the modification if the count is zero. 
       FIG. 6  is an illustration of main screen  300  when IM application icon  306  having an unread message is highlighted. Upon selection of icon  306 , in addition to highlighting the icon, a dialog box  602  comprising a message preview  604  of at least a portion of the unread message is displayed. The opening of the dialog box  604  may be briefly delayed after icon  306  is brought in focus by the user. If a dialog box is opened too quickly as a user navigates among the icons, navigation may be preempted before the user navigates to a particular icon of choice. Dialog box  604  is opened at name region  314  though persons skilled in the art will recognize that another region may be selected to position the dialog box  604 . By way of example, message preview  604  in dialog box  602  shows the application service (i.e. “AIM” for AOL Instant Messenger) the correspondent sending the message (i.e. “red 98 ”) and a part of the unread message (i.e. “See you at 4:00 . . . ”). 
       FIG. 7  shows a dialog box  602  for an IM application  306  having two unread messages indicated at visual modification  400 . Dialog box  602  comprises message previews  604  and  704 . Due to the inherent size of main screen  300  and other considerations apparent to those skilled in the art, there is an upper limit to the number of unread messages that may be previewed in such a manner. This limit may be optionally configurable by a user within a predetermined range or simply configured to a maximum size based on the available screen space, font, etc. 
     Optionally, in accordance with an embodiment of the invention, a user may be enabled to “jump” (i.e. automatically navigate) to the unread message directly from the application icon on the main screen, eliminating any intervening screens that may normally be navigated to read messages when navigating the GUI for the associated application. For example, highlighted icon  306  may be activated as per normal (e.g. selecting “enter” on keyboard  232 ) and the application initiated to start at an unread message (e.g. most or least recent). The application&#39;s initial screen or buddies list may be skipped. The opportunity to “jump” may be time-limited and enabled only for a short period of time immediately following the occurrence of the new event, such as from about a few seconds to about  30  seconds. The “jump” activation anticipates the user&#39;s need to see the unread message. 
       FIG. 8  is an illustration of another embodiment for previewing events on a main screen of a mobile station such as station  202 . In this embodiment, two new events, one for each of IM application icons  304 ,  306  are indicated via respective visual modifications  802  and  804 . Visual modification  802  comprises an event count, namely a count of unread messages and a message preview providing a sender identity and a portion of the unread message. Similarly though differently modification  804  comprises an event count and state preview indicating IM correspondent buddy Tom has signed on. Persons of ordinary skill in the art will appreciate that different events may be visualized on the main screen in accordance with the invention and these events may depend upon the associated application. However, options may be selectively configurable. 
       FIGS. 9A and 9B  are flowcharts which describe a method in accordance with the invention for the visual modification of an application icon to represent a new event.  FIG. 9A  represents operations  900  for identifying a new event to determine the modification and  FIG. 9B  represents operations  901  to display the modification. 
     Operations  900  may be enabled for a service or other application such as IM, e-mail, etc. Though not shown events to be monitored (for example, by a monitoring component of the GUI) and visually indicated (for example, by a icon modifying component) upon occurrence are pre-determined in accordance with a type or types of events to be notified and previewed. For example, for operations  900  for use in accordance with IM, whether the count is to count distinct unread messages or senders is pre-determined. 
     Beginning at a start block  902  of  FIG. 9A , operations  900  commence and the application represented by the application icon to be modified is monitored for a new event (step  904 ). Persons of ordinary skill in the art will understand that monitoring may be implemented in a number of fashions depending, in part, on operating system and other system services and the interface between communication subsystem  211  and microprocessor  238 . Each of the plurality of applications to be monitored may have a dedicated monitoring component to determine the occurrence of respective new events. Alternatively, a single monitoring component could monitor each of the applications. Monitoring may be continuously or intermittently performed repeating step  904 , until a new event is determined. 
     Upon a new event, at step  906 , the visual modification to the icon to be changed is determined by an icon modifying component. The counter, if any, is incremented and any visual element or graphic to be overlaid may be configured. For example, text may be obtained for the overlay as exemplified by visual modification  802  of  FIG. 8 . The counter may be decremented if the monitored event is the reading of a previously unread message, for example. 
     User actions that may be performed in association with the modified icon may be set up. For example, text for a dialog box may be obtained in advance and associated with the visual modification for use when the icon is highlighted on the main screen by the user. Should the icon be activated to initiate the application, data to facilitate an immediate automatic jump to the most recent unread message may also be determined in advance if necessary, and associated with the visual modification. The sender of the message may be identified and various user action options prepared for that sender. For example, actions to permit a phone call, e-mail, SMS or other selectable message may be presented to a user highlighting an icon having a visual modification. 
     At step  908 , the visual modification and any associated data, as applicable, is identified to a main screen maintenance portion of the PIM GUI or other application responsible for maintaining the main screen as described further with reference to operations  901 . The notification may pass an object or other data sharing mechanism to provide the modification and any associated action data. Thereafter, monitoring continues at step  904  of operation  900 . Monitoring may continue for as long as station  202  is powered. 
     Beginning at step  910 , operations  901  commence for main screen maintenance. At step  912  operations monitor to determine that the main screen is active. If yes, operations monitor for a user action or a notification of a visual modification to an icon (step  914 ). Upon such an occurrence, a new screen is drawn reflecting the visual modification of an icon or the user&#39;s action (step  916 , via Yes branch). Exemplary user actions are moving the focus or cursor over the icons of a main screen to highlight an icon or activating an application associated with the icon. The highlighting of an icon that was previously visually modified may further initiate a dialog box display requiring the drawing of the main screen as described above. Once the screen is drawn at step  916  or if no new icon or user activity is detected at step  914 , operations  901  repeat at  912 . At step  912 , if the main screen is no longer active, for example because a user has navigated to another screen, operations  901  may cease (step  918  via No branch) until the main screen is reactivated (not shown). 
     Operations  900  illustrate a method aspect of an embodiment of the invention monitoring events of a single application. As will be understood to those of ordinary skill in the art, mobile station  202  may be configured to have multiple monitors, one for each application, or a single monitor configured to monitor all applications for new events. Alternatively, each type of application could have a monitor for monitoring respective instances of the application type. For example, a single monitor could be configured for monitoring the three IM applications of the above-described embodiment, a further monitor may be configured for the two e-mail applications, a further for the phone application, etc. 
     While operations  910  are illustrated as waiting to be advised of a new visual modification, other initiation mechanisms could be employed. For example, each application or respective monitor therefor could be queried for new visual modifications. 
     Though operation  900  and  901  are described with reference to new events, persons of ordinary skill in the art will appreciate that modifications may be incorporated therein to expire the preview of a new event and display a default or other icon for an application. For example, with reference to  FIG. 8 , icon  804  illustrates a status event preview, namely the sign-on of Red 98 . This preview may be expired automatically after a predetermined period of time. A standard or default icon could be used to replace the preview icon. Alternatively, a modified preview icon could be used such as one indicating a count of new events. Similarly, it may be desired to persist some new event previews information even upon the happening of subsequent new events for the same application. For example, new event information relating to a status of the associated application, (e.g. sign-in/out status, availability etc.) may be persisted even as new events occur and are previewed. 
     The above-described embodiments of the present application are intended to be examples only. Those of skill in the art may effect alterations, modifications and variations to the particular embodiments without departing from the scope of the application. The invention described herein in the recited claims intend to cover and embrace all suitable changes in technology.
