Have you applied any body/skin on the back of the phone. I put the BodyGuardz on mine and I didn't get it lined up exactly right so it was sticking up on one edge, making a sharp little edge. I just trimmed it off with a very sharp razor blade.
Yeah, unfortunately there is nothing you can do about that. I had a old iPhone that was like that. Wasn't enough to bother me though. That is just the way some get manufactured. I would not even try bringing it back either. Doubtful they will do anything as the phone works the way it should. Lucky for me that my 3g is perfect. But I do feel for you if it bothers you.
Sharpe edges - hopefully limited production batch problem?
Bought a white iPhone 3g 16GB on 30DEC08. Rejected and returned due to the sharpe edges. The store finaly offered a new one a month later.
In Sweden there's an Apple policy of having consumers "buying a pig in a bag (poke)" (not allowing the box to be opened until purchase is consumated). That makes it difficult to now what to do next.
Maybe better luck with the black ones?
Hopefully it's a small production batch that has this production problem?
Silicon covers, duct tape, etc. is not the solution ;-)
The right side of my phone about in the middle the plastic curves out a bit and then curves back in. So at that spot in the middle it isn't flush with the chrome. Not a big deal as you can't even see it really, you can just feel it.
