My iPhone 4S is having a screen problem. I let it die completely one day, and didn't bother to recharge it for about 12 hours. When I did, the screen lit up, but wouldn't display anything. I'll post a picture. Now this is an aftermarket screen that I replaced my original screen with. (It's actually my third screen). It hasn't really been a very good screen; it always displayed colors a little off or had random lines going through the display, but I'm willing to put up with it until the 5S comes out. But I can't live without it working at all! My thought is something came loose inside? I need to order another pentalobular screwdriver if that's the case. I have dropped it a few times so that could be it. I thought it may be bricked, so I tried to restore it, but I have iOS 7 on it despite it not being a registered dev device, so it just wouldn't do anything. Halp!
