1. A mobile communications device configured to operate in a device mode and operate as a pointing device in a mouse mode for a computer, and comprising:
- a housing;
a display carried by a front surface of said housing;
a keypad carried by a front surface of said housing;
a low friction projection positioned on the front surface of said housing at an end opposite said display, said low friction projection protruding outwardly therefrom farther than said keypad to inhibit the keypad from contacting a mouse surface during use of the mobile communications device with the front surface down in the mouse mode;
a navigation pad carried by the front surface of said housing and protruding outwardly therefrom farther than said keypad and said low friction projection, and configured to selectively operate as a device pointer during contact with a finger in the device mode, and as a computer pointer during contact with the mouse surface in the mouse mode;
an antenna carried by said housing; and
a signal processor carried by said housing and configured todetect motion of the mobile communications device in the mouse mode via said navigation pad in contact with the mouse surface and encode motion signals based thereupon, andtransmit the encoded motion signals to the computer via said antenna.

Abstract
A mobile communications device includes an antenna, a navigation pad and a signal processor. The antenna, navigation pad, and signal processor cooperate to encode and transmit motion signals from the navigation pad to a computer so that the mobile communications device functions as a pointing device for the computer.
