S2U2 (Slide2Unlock2) is a simple lock/unlock application which has the iPhone style slide unlocking. It can be used as a screensaver while you don’t use your device. And it’s has a CallerID function.

Changes:

– added the option to lock the device when the LCD is blanked (e.g. by S2P or other music app).
– fixed the bug that the OffLCD did not work on some devices.
– fixed the bug that occasional power drain might occur on some devices when ActiveSync is running in the background.
– fixed the bug that ShowAppointment could not display any appointment on some devices.
– extended the ShowAppointment to display the next week appointments.
– fixed the bug that the registry values looked messy.
(To make it works, after the installation of this version, please run the S2U2 Settings & save the settings once.)
– some minor bugs fixed.
