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.

Updates:
- added GIF format support to Wallpapers; with option GifSpeed to control the animation speed. (there is no GIF file included in the CAB file as I don't want to get into any copyright trouble)

- added option to select a directory for S2U2 to change the wallpapers (*.jpg) automatically; with option to control the changing period & change them randomly.

- added support to display over-sized Wallpapers.

- added option to change the font of the Clock (clock, clockH or clockHS).

- added option to display an Analog Clock (clockA).

(From left to right: clockH, clockHS & clockA)

- added ARGB PNG format support to all graphics files.

- added ShowWeather to retrieve today's weather forecast from other weather applications. For UserWeather, you have to manually update the registry key UserWeather (STRING) under HKEY_CURRENT_USERSoftwareA_CS2U2. The format is "icon|index|high temp|low temp" where icon is S, P or W.

- added SIM card support to CallerID.

- added option S2AEndKey to enable/disable the End key when S2A is activated.

- added option NoSoftKey to hide all soft buttons. But how to UNLOCK? Press the RIGHT-DPAD.


- added option TopCurtain to enable/disable the display of the topbar.png.

- added the BT headset status icon.

- added an Exceptional applications list that when these applications are running, S2U2 will not start automatically. (Edit the Registry, under HKEY_CURRENT_USERSoftwareA_CS2U2, add a key ExceptionEXE0 (STRING) with the name of the application (e.g. iexplore.exe). A total of 10 (0-9) ExceptionEXE can be added. Then restart iLock2.)

- fixed the issue that DirectDraw could not be used when the device is in Landscape.

- fixed the issue when S2A is enable, the BT headset button did not work.

- fixed the issue when "Password/Pin Lock" or "Owner Information" are enabled.

- changed some wordings of "s2u2 Settings.exe"

iLock2.lnk - start/stop ilock2.exe (on the 1st run, it runs silently in the background; on the 2nd run, it closes iLock2 & S2U2)
s2u2.lnk - manually start S2U2 (be sure iLock2 is running in the background, otherwise the Battery status will not be updated).
s2u2 Settings.lnk - change the settings of S2U2.

- A shortcut for iLock2.exe is created automatically under "WindowsStartUp" as well.

- Installation on Storage Card is not recommended for the sake of stability.

- For hi-res devices, d/l the S2U2ClockPack.rar & follow the steps in the ClockReadme.txt. Otherwise the clock will be shown as half-sized.

- For additional clock fonts, d/l the S2U2ClockPack.rar & follow the steps in the ClockReadme.txt.
