Here's the issue, my girl dropped her new Iphone 3GS from a height of 2 feet onto a carpeted floor. Now it's got the white screen of death. I tried everything from updating the operating software to 3.0.1 to restoring it back to factory settings. Nothing worked. I started to shake a bit and heard a tiny rattle inside. Seems something may have come loose or broke off internally. My question is I am suppose to take this to the apple store to have it looked at it tomorrow. Is there any way that I can open the case at the top (just the 2 screws) and see if I can shake the little rattling part out? Will they know I opened the phone? Trying my best not to pay $200 for another one because this thing can't take a tiny drop. P.S. She had a case on it too to cushion the fall Any help is greatly appreciated, thank you!!!!
