Phone randomly shuts off

[kahluachno]

so this problem was happening to me too so i followed the directions below but when i still hold the end call red button it still turns off my phone. do i need to do something else to disable this function?

HOW TO: Permanently Disable Flight Mode

You must have a registry editor installed on the PPC. I used PHM RegEdit
Go to the registry and change the following key:
HKEY_CURRENT_USER -> ControlPanel -> PhoneExtendFunction -> CDMA

Change FlightModeSwitchByPnHEndKey to 0

This will prevent the phone from going into Flight Mode if you accidentally press the End Call button for too long.

Note that Flight Mode can still be used by tapping the signal strength meter. (I wish I could disable that too)
