Hey, So I'm having an issue with my iPhone 3G. Needless to say, Rogers is swapping it. I had it jailbroke in the past, but is there anything I should do to make sure everything goes smoothly? (It's no longer jailbroke and is on 3.1.3) Other then that, sometimes when touched the back of the case where hteh ome button would be I hear a little "click" if I press on it... Think Apple would charge me for this?
