Slide2Unlock2 (S2U2) 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.
S2U2 Customizer is just a initial test to know the responses. Currently changes only to Digital Clocks & Arrows plus an option to backup the current theme & restore the previous theme is available.
