First of all, I waiting on friday morning and love my iPhone 3G. Today I noticed that if I shake the phone I can hear something moving inside it. I know that this is such a small thing but it bothers me so I thought i'd go ahead and ask. The noise doesn't happen when i slowly move the phone or rock it back and forth, but only when I give it a decent shake. And only when I move the phone vertically, not side to side. It sounds like something very small and light, definitely not the battery. I'm pretty much a noob, the only thing i can think of is maybe the accelerometer, but I didn't think that it would have enough play in it to make a noise, and my first gen I phone definitely didn't do it. Should I bother going to my local apple store or is this something I shouldn't worry about?
