Abstract

A system and method for pushing information from a host system to a mobile data communication device upon sensing a triggering event is disclosed. A redirector program operating at the host system enables a user to continuously redirect certain user-selected data items from the host system to the user'"'"'s mobile data communication device upon detecting that one or more user-defined triggering events has occurred. The redirector program operates in connection with event-generating applications and repackaging systems at the host system to configure and detect a particular user-defined event, and then to repackage the user-selected data items in an electronic wrapper prior to pushing the data items to the mobile device. The mobile data communication device may originate new messages or reply messages to previously received information, such messages being transmitted to a wireless redirector host system, which then transmits a copy of the messages to both the intended recipient and a first electronic mail account associated with the mobile data communication device.
