I just got mine at Apple store. I opened the iPhone 5 black 32gb AT&T and there was a small nick on the bottom left corner (Nothing major and in reality something that I could put up with - But I waited 13 hrs so I wanted a flawless one)
I immediately asked for another one. Lady working there seemed somewhat annoyed but got me another one. Thankfully the second one had NO flaws =)
Nice. Don't hesitate to ask for another. You guys waited in line/spent hundreds of dollars; you deserve to get what you paid for.
Sorry to hear about all these scuffs guys. I wonder if Apple will even address it, or if they'll look the other way until the 5s comes out and say "now made with more durable material"
