My wife was downloading wallpaper apps from the market and now her unlock slider bar is missing. When you bring the phone out of sleep, it goes directly to the home page. The bar that you slide to the right to unlock and the one you slide to the left to turn ringer off is gone. Also when you hold the power button down to bring up the phone options, the airplane mode is missing. the only option i have is phone off. and when i call her it goes straight to voice mail. this is why i think it is stuck in airplane mode. any help is apprieciated.
