Mobile communications device employing multiple data storage locations for electronic messages

A method for routing message data within a mobile communications device comprising:

• receiving at least one incoming message via a data service network;
• comparing the contents of the incoming message to at least one criterion contained in at least one message routing rule having a message database object associated therewith;
• storing the incoming message in the message database object associated with that message routing rule if the incoming message meets each criterion for the message routing rule;
• and
• storing all messages not routed to a message database object associated with a message routing rule into a default message database object.

A system for routing messages to a mobile communications device comprising:

• a first message database object, disposed within the mobile communications device, containing a first set of message data;
• a second message database object, disposed within the mobile communications device, containing a second set of message data;
• means for receiving new message data from a source outside of the mobile communications device through a wireless data service network;
• means for selecting a destination for the new message data from the first data storage space and second data storage space based upon at least one message routing rule;
• and
• means for routing any incoming message not meeting a message routing rule to a default message storage object.
