TP2 signal keeps cutting off?
 

My Touch Pro2 used to have anywhere from 3 to 5 bars of signal at any given time. Now, it keeps jumping from 0 to 1 bars of signal. Whenever I try to update the weather, the signal icon at the top of the screen flashes and is accomanied by a G. Afterwards, all data connections are turned off until I activate it manually from the Comm manager.

Does anyone know what's going wrong?
