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. It has a CallerID function (but some devices may not work, so please try it first); S2P control plugin; and volume control.


– fixed when CallerID was off, system might hang after receiving an incoming call.
– fixed the S2U2 Settings could not browse pics/files.
– reverted the sound codes (lock/unlock sound) for faster performance, but also removed the support to MP3.
– non-exist wallpaper file setting will show a black background.
