Hi guys 10 days ago I've sent my iPhone 3GS back for replacement because SimCard Slot wasn't aligned with the rest of the case: it was a little bit out (it's not like it's very noticeable, but you can clearly feel it with your hand). I was told by Apple that when you eject the SimCard slot the first time, a temporary piece of plastic should came out, and that wasn't my case (we thought that it was somewhere there inside, blocking my SimCard). So replacement has been made. Now I have my new 3GS in front of me and it has the same problem. I've attached few photos so you can see better... Question: is it "by design"? Do you have this imperfection too? Should I replace it again?
