My toddler was playing games in my bed this morning. He is normally quite good with the phone and has his own apps to play. Anyhow about 15 minutes later I took the phone from him and instead of seeing the bottom layer icons that are static across screens I see a gray box. It appears darker at the top and gets lighter to the bottom with the number of tiny dark dots getting smaller as they get to the bottom. At the very bottom of the screen is a dark bottom line. Anyone with experience with this? So far I have tried resetting it. iPhone 3G.
