Have a question regarding replacement iphones. I have a iphone 3g, but it's unlocked and I'm using it on Tmobile. How do I go about getting a replacement iphone if my accelerometer isn't working properly (safari stays in landscape, caculator, etc.) I bought it brand new out of the box from a guy, so it's never been "activated." I searched Apple's website and confirmed that. I was going to take it to an Apple store, but they said I needed to bring my sim card, and obviously I don't have ATT. I'm apprehensive about giving my serial number over the phone to an Apple representative till I know I'm not going to be black listed. I don't want to look fishy when they ask how do I know my accelerometers don't work and it's not activated. Note: I've already tried restoring the phone and seeing if the accelerometers work. I even purchased an accelerometer application which indicates my phone is stuck in left landscape. If anybody has any guidance on how to "fix" my accelerometer issue or how to go about getting a replacement phone, I'd really appreciate it.
