I have a third gen ipod touch. I have had it in a case and have never had any problems with it, but recently I have noticed that there is dust on the screen that is under the digitizer. I am not sure how it got there but I cannot get it off. there a way that I can get this off of my ipod screen without opening it up. I cannot see it except for when the ipod is off or when I am at a dark screen. It can get really annoying Please help! If need be I can try to take a photo of this to help you guys see it. Rules!
