A method of adapting a phone profile in a wireless communication device to a caller identifier (Caller ID) signal, comprising the steps of: extracting Caller ID information from a received Caller ID signal; associating at least a portion of the Caller ID information with a first predetermined profile or a second predetermined profile of a plurality of predetermined profiles stored on the wireless communication device, wherein associating the portion of the Caller ID information with the first predetermined profile or the second predetermined profile comprises associating Caller ID information with settings and applications for a first particular user corresponding to the first predetermined profile or with settings and applications for a second particular user corresponding to the second predetermined profile; and enabling access to the first predetermined profile only when the portion of the Caller ID information is associated with the first predetermined profile and access to the second predetermined profile when the Caller ID information is associated with the second predetermined profile; characterized by: storing on the wireless communication device the plurality of predetermined profiles, including the first predetermined profile and the second predetermined profile, relating to the first particular user and the second particular user of the wireless communication device, wherein the first predetermined profile is associated with the settings and applications for the first particular user and the second predetermined profile is associated with the settings and applications for the second particular user, and wherein the first particular user and the second particular user share the wireless communication device; switching between the first predetermined profile and the second predetermined profile based on whether the Caller ID information from the received Caller ID signal corresponds to the first particular user or the second particular user; and denying access to the predetermined profile based on a password or hardware or biometric security associated with the profile selected by Caller ID information. extracting Caller ID information from a received Caller ID signal;
