Locking was never so fun! G-sensor has really made it in that way.
SensorLock is a program designed for the HTC Touch Diamond (and will probably work on the HTC Touch Pro too). SensorLock allows you to lock the device’s screen and buttons, thereby preventing random button and screen presses while the device is in your pocket.

Locking and unlocking is simply done by rotating the device around its longest axis (clockwise for locking and counter-clockwise for unlocking) and can be done in any program (Media Player, TomTom etc) without disrupting normal device operation.

Updated version 0.4.0

The complete list of improvements this release brings:
* Added gesture recorder, gestures can now be user defined.
* When stylus is pulled out when device is asleep, autolock no longer locks the device.
* Autolock everything no longer displays the message to shut down the phone when switching on the phone.
* The notification padlock icon is now optional and may be disabled in the control panel.
