i know on the Sprint Mogul, if you go into the registry under HKEY_CURRENT_USER, go to ControlPanel, then PhoneExtendFunction then CDMA, and in the CDMA folder find FlightModeSwitchByPnHEndKey and change the value from 1 to 0 it will allow you to hold the "end call" button for 3 seconds to shut off the data connection. if you hold the end key for 5 seconds it'll put the phone into Flight mode, at which point you can press the end call button for another couple of seconds and the phone connection comes back on.
