First Claim
1. A telephone device integrating a first processor and a second processor, comprising:
- a main processor for executing a plurality of user applications including a phone application and at least one of other applications;
a baseband processor for executing a phone control application of the telephone device; and
a communication link coupling said main processor and said baseband processor for transferring data and command signals, wherein, the main processor executes the following steps;
allowing a user of the telephone device to select one of the plurality of the user applications;
booting the selected user application on the main processor; and
booting the phone control application on the second processor if the selected application is a phone application.

Abstract
Separate processors, a PDA processor, and a baseband processor are maintained in a PDA having an integrated telephone device. The PDA processor runs PDA related programs and a user interface for the telephone device. A link between the PDA processor and baseband processor transfers data and commands from the user interface to a phone control program executing on the baseband processor. The base band processor is connected to the telephone device, and the phone control program controls operation of the telephone device. The separation of processors reduces vulnerability of the telephone device to hacker rogue applications that invade or program crashes that occur on the PDA processor.
