MOBILE COMMUNICATIONS DEVICE EMPLOYING MULTIPLE DATA STORAGE LOCATIONS FOR ELECTRONIC MESSAGES

A computer readable medium encoded with computer executable instructions thereon for execution by a processor of a mobile communication device (116) comprises a code segment (216) for message processing, which may include a code segment for rule comparison, a code segment for message routing and a code segment for default message handling. The message processing code segment (216) processes an incoming message received via a data service network (400). The message processing code segment (216) subsequently compares a portion of each incoming message to at least one criterion contained in at least one message routing rule having a message database object (418, 420) associated with it, stores each incoming message meeting each criterion for a message routing rule in the message database object (418, 420) associated with that message routing rule, and stores all messages not routed to a message database object (418, 420) according to a message routing rule into a default message database object (422).
