Abstract: A delivery platform delivers data from a remote data source to an application on a mobile device. In response to requests from the application, the delivery platform retrieves the data from a remote data source and stores it in a local database. Corresponding metadata is stored in a metadata database. The delivery platform delivers to the application a view of the retrieved data that is based on the retrieved data stored in the local database and on the metadata stored in the metadata database.

Abstract: Methods and apparatus consistent with the invention provide the ability to organize a plurality of user identities on a mobile communication device and to process messages for a plurality of user identities on a mobile communication device. A first-level user interface allows a mobile communication device user to access multiple user identities. Responsive to a selection of a user identity, a second-level user interface including a main data screen associated with the selected user identity is displayed. Responsive to a user selecting data from the main data screen, a third-level user interface is displayed to allow user examination of the selected data. Received messages are categorized and associated with a user identity based on the classification result.
