Hello, Here is my issue. Last year I bought the 16g first gen Iphone. About 2 weeks ago, I noticed a group of small grey bars at the top of top of the phone (ranging in thicknees, probably 1.5 mm at its thickest). It almost looks like somebody digitally chopped off the top of the screen. I tried restarting the phone, and even restoring it to no avail. Has anyone heard of this issue? Sounds like a pixel problem. I have an appointment tomorrow at the Apple store, and luckily I'm just within the one year warranty. However, I just want to make sure this isn't something I would have caused directly thus nullifying the warranty. Thanks!
