Where is the registry entry for holding down endkey/flightmode in 3.56?

[riphamilton]

By default, holding down the end key in 3.56 puts the phone into flight mode. Obviously it's a lot more useful if instead it terminated your data connection.

In previous roms to do this, you could simply go to HKCU\ControlPanel\PhoneExtendFunction\CDMA\ and change the FlightModeSwitchByPnHEndKey from 1 to 0.

That registry entry doesn't exist in 3.56, and I spent over an hour last night going through the registry looking for its replacement; couldn't find it.... plus, the "long press end key" .cab from the HTC Touch doesn't work with winmo 6.1 (presumably because it simply edited the above key).

Any other ideas as to how one could get the end button to terminate a data connection? Thanks!
