I got my second replacement. Four little dots around the bezel but I decided to live with it. Got home and checked the back and saw this though. What do you guys think it is? It looks like a smudge but it won't wipe off (the mark next to the flash is a piece of hair. I'm referring to the cloudy smudge towards the middle of the glass). I was going to go the next day for a third replacement but figured the genius would say that this was too minor Sucks that my original five was more pristine than the first and second replacement.
