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 (but some devices may not work, so please try it first); and S2P control plugin.

Although S2U2 is now called v1.03, it doesn’t mean it can be run perfectly on your device. Thanks to different devices produced by different vendors. So, please test it before use it everyday, especially the CallerID function.

Changes:

– fixed the bug introduced in v1.02 that the clock did not update occasionally on device wake up;the idle time out occasionally malfunction; and the wallpaper did not change occasionally.
– the total unread count for FlexMail now reads to a maximum of 10 storages.
– fixed the bug that displayed night icon for Spb Weather.
– fixed the bug that some devices could not run probably on landscape mode.
– added support to RealVGA.
– added support to WVGA & WQVGA.
– some minor bugs fixed.
