1. A portable phone device comprising:
- a first portable phone housing, having a user interface, at least a microphone and speaker, and a cellular transceiver therein, said cellular transceiver operable to transmit signals from said microphone to a cellular network and receive signals from said cellular network and couple them to said speaker, and also having therein a second transceiver, operating to consume a lower power than said cellular transceiver, said second transceiver having a unique device address which uniquely identifies said second transceiver from other transceivers, operating in a multiple access system using time slots over a spread spectrum protocol (X), said second transceiver enabling operation with a remote device which changes a mode of operation of said telephone to a changed mode of operation;
wherein said user interface on said portable telephone includes an initiation button which is actuated to initiate a communication using said second transceiver.

Abstract
A system for operating a cellular phone using Bluetooth with a car kit is described. The Bluetooth protocol is used to communicate between the cellular phone and the car kit. A communication can be established between the cellular phone and the said car kit. In one mode, the car kit can be made to assume the identity of the cellular phone and transmit as if it were the cellular phone itself. In another mode, the car kit can become a hands-free set for the cellular phone which communicates with the cellular phone via Bluetooth.
