A little application that will turn off the cellular radio during certain times of the day. The goal is that this will help preserve power and extend the life of the battery.

Copy the cab file to your device using ActiveSync and run the cab file locally on the device using the file manager. Once this is done you can run RadioOff from the start menu. To use the application set the times you want the radio to turn off and on (mine is set to turn off at midnight and turn back on at 7:00 am), then press the start button
