My son just purchased the 8GB with his own money 3 days ago. Last night the battery was getting low, so my husband turned it off. We recharged thru an iHome and this morning it won't turn back on. I tried pushing the power and home buttons at the same time, and it seemed to work. An apple symbol with a line thru it for a few minutes, then okay. I already had it plugged into the computer with the USB, so it went into a sync too. Even though all seems ok for now, I'm planning to exchange it. We shouldn't be having to do this on a brand new device.
