I noticed a rattle in my iPhone4 today. It sounds like something small is loose inside the casing. /edit/ Its the power button. When I shake the iphone it rattles, but when I hold the power button and shate there is no rattle. I have the iPhone since launch last year, and I've confirmed its out of warranty. I was thinking of taking apart the phone to see what is rattling around inside. Is this; (a) a good idea, and (b) a difficult thing to do? Is there anything else I can do? Any ideas on how to fix this or whether or not Apple would repair/replace are greatly appreciated. Would taking the phone apart be a way to fix this? Its probably a small thing, but I know it'll drive me and my OCD crazyyyyyyy ...... Thanks in advance for all answers/suggestions.
