I couldn't find this problem addressed before, but I apologize in advance if my search wasn't comprehensive enough. I just picked up a brand new 3GS from AT&T store today for my girlfriend. Right away I noticed that all the keys on the keyboard had a small dark dot/pixel. Upon closer inspection, there are more "distorted pixels" (I can't think of what else to call it), most noticeable on the keyboard but present in other areas as well. See my attached screenshots. A full restore to factory settings (including upgrade to iOS 4.0.2) did not fix the problem. Anyone experience this? Do I have a faulty unit? Thanks.
