CallerID

Q. Does the CallerID support Video Call / Skype / PTT (Push-To-Talk)?
A. No.

Q. The CallerID function does not work on my device?!
A. Since there are a lot variables between different devices/environment, it's possible that the CallerID does not work.
So test it before daily use. Not only test whether the proper Caller could be display, also test the Answer/Ignore response. And if it does not work, disable the CallerID. Otherwise you'll not know who is calling and you may not able to Answer/Ignore a call.
A. If your device has OEM CallerID installed (usually done by the manufacturer), you may try to disable it by changing the registry HKEY_LOCAL_MACHINE\Security\Phone\Skin\Enabled to 0. Then soft-reset & try to enable CallerID again. But it will also disable the dialer skin as well. 

Q. The quality of the CallerID pic is so bad even the original photo is in high resolution?!
A. DO NOT use the system contact/outlook to add photo to a contact. Use S2V (Slide 2 View) to do so.

A. Press the Volume Up/Down; or DPAD Up/Down keys when option DpadOn is enable.

Q. After soft-reset, sometimes the first call's callerID is not shown?
A. It's an OS issue, no solution yet.

Q. The CallerID is working fine, but after iLock2 is ended, no more CallerID even the system one?

A. Change the setting of "Slide to Answer" from "Only Locked" to "Always".

Q. CallerID is already turned on, but the hardware keys are not locked when there is an incoming call?
A. Set "Slide to Answer" to "Always" (S2U2 Settings > Phone); and turn off both "S2A Hard Answer Key" & "S2A Hard End Key". But it may also block the answer key of Bluetooth handsfree device.

Q. How to change the busy SMS message?
A. Open the lang.ini (under the S2U2 installed folder), edit the s_BusySMSBody tag. The lang.ini must be saved in UNICODE format. Restart iLock2 to load the changes.

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 cannot be shown?
A. Currently, there is a limitation to the size of the GIF file. Sometimes, even your device has enough free RAM, it still cannot be shown. Suggest to reduce the dimension (not the file size) & the no. of frames in the GIF, then try again.
A. Turn on "Override GIF Speed" (S2U2 Settings > Wallpaper).

Q. The GIF animation stopped after a certain period?
A. Turn on "Endless GIF Animation" (S2U2 Settings > Wallpaper).

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, HTC Manila (TouchFLO) 2D & 3D Weather, and Elecont 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. For e.g. "C|50|Rainning" means the \gfx\weather\50.png icon & "Rainning" will be displayed on screen.
A. Schettj has created a MortScript to update it through Yahoo's weather, details at http://forum.xda-developers.com/showthread.php?t=358952
A. michoob has also created a MortScript called IPTWeather to display details weather info on S2U2, details at http://forum.xda-developers.com/showthread.php?t=603817

Q. Which weather applications can show current weather info on S2U2?
A. S2U2 v2.33 or later supports to show current weather info from Pocket Weather (thanks Adrian for the excellent support), HTC Manila (TouchFLO) 2D & 3D Weather, and Elecont Weather.

Q. Why other weather applications cannot show the current weather info or even the weather forecast?
A. Since each weather application has its own way to store the weather info, it's hard to decode or guess the desired weather info from an outsider. So, unless the developer of the weather application is willing to expose the technical details on how to retreive the detail weather data, otherwise it's not possible for S2U2 to get the weather info.

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 (TouchFLO) 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.
