On WM6.5 and WM6.5.x you have the option of using the new sliding lock screen. You might prefer to use the old 'Windows Classic' lock screen (i.e. the one where you have to tap the soft key then an unlock button like in WM6.1), as it uses less memory and allows you to see the today screen. However, on many ROMs for HTC phones, even stock ROMs, it doesn't seem to work properly with regards to incoming calls.
When you receive an incoming call, the lock screen pops up asking you to tap unlock, but it is unresponsive and obscures the caller ID screen, meaning you can't see who's calling you or the accept / reject slider. On phones / ROMs were it does work properly, you sometimes still have to press the unlock button manually before you can do anything.
DeviceLockXT is the solution to this problem. The program basically just sits and waits for an incoming call, and when the system notifies it of one, if the device is locked it waits for the unlock screen to pop up and then very quickly presses the '*' key. The result is that the device unlocks before the screen messes up, allowing you to see the dialer! The app is very lightweight (executable is only ~6KB), fast (native code), and does not use the CPU whilst idle since it makes use of the windows messaging notification system. Should theoretically work on any resolution on any device.
