A method for providing a respective customized application to a plurality of user terminals (1-80; 6-80; 7-80 1... 7-80 n; 9-81), each of which comprises a web browser, wherein the customized application is customized in respect of at least terminal-specific properties and user-specific parameters, and the plurality of user terminals comprises at least a first user terminal and a second user terminal, the first user terminal, which is not the same terminal as the second user terminal, stores a version of the customized application; the method comprising: - an application server storing identifying information on the user terminals and/or their associated subscriptions; - the application server storing a template for the customized application and a feature set for each of several terminal types, wherein the template defines functionality of the customized application; - the first user terminal sending a community message to the second user terminal, which is selectable via a user interface of the first user terminal; wherein the community message comprises a link for directing the second user terminal to a network address of the application server; - wherein activation of the link in the second user terminal initiates transmission of an http page request (2-14, 9-6) by the web browser to the application server for creation of the customized application; - the application server determining identifying information of the second user terminal and/or its associated subscription, and a type of the second user terminal based on the http page request (2-14, 9-6) for the customized application; - the application server determining the terminal-specific properties based on the determined type of the second user terminal; - the application server determining the user-specific parameters; - the application server creating the customized application based on the template and the terminal-specific properties and the user-specific parameters; - wherein the customized application comprises a feature to send the community message to at least one further user terminal other than the second user terminal, which is selectable via a user interface of the second user terminal; and - inserting the customized application into a set of delivery files for a data communication system and transmitting the set of delivery files to the second user terminal along with a manipulated header, as a result of which the application server is able to send the customized application as a response to the http page request (2-14, 9-6); - whereby the respective customized application automatically includes the functionality of the customized application, the terminal-specific properties and the user-specific parameters. - an application server storing identifying information on the user terminals and/or their associated subscriptions; - the application server storing a template for the customized application and a feature set for each of several terminal types, wherein the template defines functionality of the customized application; - the first user terminal sending a community message to the second user terminal, which is selectable via a user interface of the first user terminal; wherein the community message comprises a link for directing the second user terminal to a network address of the application server; - wherein activation of the link in the second user terminal initiates transmission of an http page request (2-14, 9-6) by the web browser to the application server for creation of the customized application; - the application server determining identifying information of the second user terminal and/or its associated subscription, and a type of the second user terminal based on the http page request (2-14, 9-6) for the customized application; - the application server determining the terminal-specific properties based on the determined type of the second user terminal; - the application server determining the user-specific parameters; - the application server creating the customized application based on the template and the terminal-specific properties and the user-specific parameters; - wherein the customized application comprises a feature to send the community message to at least one further user terminal other than the second user terminal, which is selectable via a user interface of the second user terminal; and - inserting the customized application into a set of delivery files for a data communication system and transmitting the set of delivery files to the second user terminal along with a manipulated header, as a result of which the application server is able to send the customized application as a response to the http page request (2-14, 9-6); - whereby the respective customized application automatically includes the functionality of the customized application, the terminal-specific properties and the user-specific parameters.
