The back part of my iPhone has a sort of "clicky" casing on the back, and I am not sure if I should return it. Whenever I hold it in landscape position, I always hear the click. It clicks right near the dock connector, but is starting to move up into the middle of the black part. I think I should return it just in case of future mishaps that might come along with the clicky casing, but maybe it is too miniscule of a problem.... but I do have bad OCD, and that makes this problem really annoying for me... Would I be able to return it easily if I did return it? Do I have to go through the activation process again, or do they just give me a new iPhone and then swap the SIM card?
