iPhone 2G won't stop rebooting
My iPhone 2G seems to be having some major issues. When it is unplugged, it won't turn on at all. If I plug it in to the USB, it won't turn on at all. If I plug it in to the wall charger, it turns right on and shows me the apple logo, but after 5 seconds it reboots itself and keeps rebooting every 5 seconds until I unplug it, at which point it goes back to not turning on. I have left it on the charger for a few hours in the thought that it might need to be charged, but it makes no difference. Any ideas what I should do now? I am guessing that the logic board is probably OK or it wouldn't give me the logo, right? Could this be a bad comm board or a battery problem?
Any ideas you might have (besides 'get a new phone') would be appreciated.
