So ups dropped my 32gb black iPhone at my office today at around 930. Really nice to get it so early and right away I opened it and activated it. Then I carefully inspected it and noticed some things. Piece of dust under the camera lens, nick here, scratch there and a little discoloration on the bezel. Probably sounds worse then what it actually was so I went back to work thinking nothing of it. As the day went on, these imperfections started to get me so I decided to go straight to apple after work. I walked in and told them and showed them. They brought a replacement out, no questions asked. After inspecting the replacement, the employee found some marks and brought it to the back. About 15 minutes went by and finally comes back with one that was flawless. Said it took him a few phones to find it. They have extras in the back for service problems that are not for sale. What I am saying is that if there is something wrong and it bothers you, bring it in. Even if they are sold out they have service replacements for manufacture defects. Hope this helps.
