I've got this weird... mark... under the screen of the iPhone 3G. http://img210.imageshack.us/img210/9522/1010787kb3.jpg When you push on any part of the screen, the thing starts to swirl, almost how it looks when you directly push on an unprotected LCD screen. It's extremely visible under direct light, as shown in the image, and I also have a stuck pixel on my screen. You think Apple will replace my unit? Does anyone else have this?
