I got my iPhone 4 last Wednesday and noticed that it had some damage. Behind the glass of the Home button was a 1/4" slightly curved scratch or tear. There was absolutely no damage to the surface glass (verified by examining the area at different angles). The Genius Bar at the nearest Apple Store, two hours away, looked at it and replaced it outright. I got it home and removed the plastic film from the front and saw there was ANOTHER imperfection under the surface layer. This one is smaller, located in the upper right corner of the display, above the battery indicator, running along the bezel there for a millimeter or two. That makes two iPhone 4's, both with something wrong behind the glass layers on the front. Has anyone seen similar damage on their iPhone 4?
