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.

Changes:

– added animated transitions.
– added Password lock, set/change the password via S2U2 Settings.
– added option to ask to send a busy SMS after rejected an incoming call. The default content of the busy SMS is stored at lang.ini (make sure the lang.ini is saved in UNICODE format).
– added option to hide S2P control even S2P is running.
– added options (AppointmentLine & AlignAppointment) to change the format the Appointment info shown.
– optionally to display the operator’s logo.
The logo filename must exactly match with the operator’s name with PNG extension (e.g. orange.png); it must be placed under the folder GFXOperator;
For QVGA device, the logo has to be smaller than 16 pixels high; while for VGA, it has to be smaller than 32 pixels high.
Since there are a lot of operators in the world, only a few samples are included in the installation.
To switch back to display operator in text, delete the Operator folder & restart iLock2.
– added optional Haptic Feedback, but it may not work on some devices.
– added a flight mode icon.
– added to show the caller number property when the system found it.
– added a second-hand to analog clock – “clockAS”.
To turn it on, the clock folder must have cs0.png ~ cs14.png.
To turn it off, remove cs0.png ~ cs14.png from the clock folder.
– added a Diamond-style clock – “clockD”, but no flipping animation.
Both new clock styles are included in the S2U2ClockPack.rar (QVGA or VGA).
– removed options “BlankStart” & “SafeMode” which caused confusion & malfunction in the past.
– fixed the Home key lock of Touch Diamond/Pro/HD.
– fixed the occasional problem that under Power Save mode,
the device behaved weirdly when another program running in the background (again).
– “NoPowerSuspend” now works under Power Save mode as well.
But not sure will the power be saved anymore as they are conflicting each other.
