Whelp, I thought I was one of the lucky ones who had a perfect iPhone 5 (AT&T, black, 32GB). No scuff marks, no rattling, no screen issues, etc. Unfortunately, as I'm browsing the web on my phone today I notice a black spot on the bottom center of the screen. Go to wipe away the mark and it doesn't move ...unfortunately, it's a speck of dust under the screen. If I make a genius bar appointment, I shouldn't have any trouble getting it replaced, right?
