Did you keep it or swap it out ?
The first one had a huge gouge on the front side edge and I refused to take it at the store.
They opened up this one and everything looked fine in the store until I got home and took the plastic off the front and back.
This one has a very tiny silver scuff showing through on the front edge near the home button and a small damage area on the back where the glass meets the metal.
You have to look hard to see these areas but they are there. This is the third black 64GB I've had and they all had some form of damage one way or the other.
This one operates real nice and the battery seems to last way longer then the others so I hate to take a chance on an exchange. My OCD is saying exchange but I might just keep it.
We have thousands of dollars of Apple products and this has to be the worst quality control I have even seen from Apple.
The odds are against you getting a "Perfect" black model.
Still not sure if I should exchange this one or not.
