Hey MacRumors, I recently exchanged my Black 32GB iPhone 5 because of a scuffing issue. The first iPhone 5 I had was Model MD636LL which was scuffed and I just found out the replacement I got from the Apple Store is Model ND295LL. I thought the models are supposed to be the same since they're basically the same iPhone. This is bugging me because I'm afraid there could be differences between the two phones. I'd rather exchange my retail box for a new retail iPhone but the Genius didn't ask for it and got a replacement iPhone from a white box. Could the people who got a replacement tell me their model number for the Black 32GB iPhone 5? Thanks!
