A. It's a known limitation. Spb RA relies on the system notification bubble to literate its own alarm.
 But if "Lock Notification" is turned on, S2U2 will force the notification to background & Spb RA will be misleaded
 and think that notification is already dismissed. So, if Spb RA is used, "Lock Notification" must be turned off.

Q. How to customize the application opened when "slide to view"?
A. They are under HKEY_CURRENT_USER\Software\A_C\S2U2\S2VEXE, named 0File, 0Parameters, 1File, 1Parameters,... 8File, 8Parameters.
 0 - missed call; 1 - voice mail; 2 - SMS; 3 - MMS; 4 - email;
 5 - Flexmail; 6 - WL Messenger; 7 - reminder; 8 - active task.
 e.g. when there is a missed call, open iContact's call history instead of the system call history,
 edit 0File to \Program Files\iContact\iContact.exe;
 and 0Parameters to -recents (the path may be different on different language device & where it's installed).

Q. What is the "Vibration LED"?
A. It's the LED responsible for the vibration.
 If S2U2 does not vibrate even "Haptic Feedback" is turned on or "Vibrate On Connect" does not work,
 try to change the value of the Vibration LED; then turn on or off the "Haptic Feedback" to test it.
 e.g. the Vibration LED of Omnia is 11.

Wallpaper
=========
Q. How to change wallpaper? 
A. Create a jpg file with resolution the same as your device
 (QVGA is 240 x 320; WQVGA is 240 x 400; VGA is 480 x 640; WVGA is 480 x 800);
 rename it to "wallpaper.jpg"; copy it to the gfx folder (default is \program files\s2u2\gfx\);
 restart iLock2. And the file "wallpaperL.jpg" is for the Landscape mode.

Q. My GIF wallpaper does not shown?
A. Currently, there seems to be a limitation to the size of the GIF file.
 Sometimes, even your device has enough free RAM, it still cannot be shown.
 Recommended to reduce the dimension (not the file size) & the no. of frames in the GIF, then try again.

Q. The GIF animation stopped after a certain period?
A. Turn on the GifEndless option.

Q. I've set up a folder of GIF files & set the Wallpaper point to that folder, but S2U2 shows nothing?
A. Wallpaper(L) folder only supports JPG files.

Q. When the wallpaper is set to GIF file, even a small one, the memory usage is very high?
A. Yes, all the frames need to be cached in memory. So the more frames the GIF has, the more memory will be used.

Weather
=======
Q. My XXX weather application cannot be shown on S2U2?
A. S2U2 only supports Spb Weather 1.x (not 2.x; not Traveler; not Shell), Weather Panel, Pocket Weather, HTC Weather,
 User-defined Weather and HTC Manila 2D & 3D Weather.

Q. There is no registry key called UserWeather in my device?
A. Create it (as STRING) by yourself.

Q. How to make use of UserWeather?
A. You have to manually update the registry key UserWeather (STRING) under \HKEY_CURRENT_USER\Software\A_C\S2U2.
 The format is "icon|index|high temp|low temp" where icon is S, P or W (Spb Weather, Pocket Weather or Weather Panel).
 Or "icon|index|string" where "icon" is C (custom), "index" is the weather icon
 & "string" will be the message displayed underneath the weather icon.
 e.g. "C|50|Rainning" means the \gfx\weather\50.png icon & "Rainning" will be displayed on screen.
 Schettj has created a MortScript to update it through Yahoo's weather,
 details at http://forum.xda-developers.com/showthread.php?t=358952

Q. Why there is no current weather info shown? Why the weather icon mismatches with HTC Weather or Manila 2D/3D Weather?
A. Because S2U2 only shows TODAY's FORECAST info from other weather applications.

Q. When getting temperature (in Celsius) from HTC Home or Manila 2D, there is always 1 degree discrepancy?
A. That's the bug of HTC Home or Manila 2D when converting the readings from Fahrenheit to Celsius.

Q. The Manila 3D Weather info not shown on S2U2?
A. Check if you have added custom city; try to add a non-custom city.
A. Check if you have set the weather to update itself automatically; try different setting.
A. No perfect solution yet.
