I have an iPhone that was dropped in water. Once the backlight level goes below a certain point, the screen is completely black/useless. I need to go in iFile or some other file system browsing software to set the brightness level to 80% or something high. I've looked around and found the backlight level for SB Settings but I'm not sure if that will work. Anybody know where that setting is?

This question came from our site for computer enthusiasts and power users.
User > Library > Preferences. The property is called "SBBacklightLevel2" in the com.apple.springboard.plist file. Thanks @Andrew Larsson for the confirmation of this.
