deltaLock locks your Pocket PC's screen and buttons while it's in your pocket playing music or doing whatever would require it to stay switched on.
To lock your screen simply launch deltaLock and your screen will turn off. To unlock your screen again, press and hold down two hardware buttons. The default IDs of these buttons are 195 and 198, which correspond to the "Windows" and "OK" buttons of a HTC Blue Angel but may vary with different hardware.
deltaLock is distributed under the GPL, so you might also consider it freeware. I'd love to get some feedback, so I can further improve my program!
To install, download the binary below, extract the zip file, then run the included cab on your Pocket PC. Note that you need the Microsoft .NET Compact Framework V1.0 (or any later version) to run deltaLock.

Things to try
- battery draining faster while using deltaLock? Don't forget to turn your phone off after locking.
- why not assign a hardware button to run deltaLock? Look in Start > Settings > Buttons.
- deltaLock has various locking modes. Don't like the default? Try out another.
- looking for an easier way of unlocking your phone? Assign the same button to both unlock button IDs.
- don't like having to switch on your phone before being able to unlock it? Set your device to wake up on any button press.
- receiving extra button ids when configuring? Tell the configure program to ignore them.
