I have an iphone 1G, recently it started continuously rebooting when I unplug it from the computer. A few seconds after unplugging it shows me the red slider bar to turn it off. If I ignore, it turns it self off (screen goes blank) and turns back on get the apple logo and again the slider bar. This goes on in a continuous loop. When I plug it in to the computer, it works perfectly fine, itunes recognizes it, I can sync stuff and everything. I tried to restore it to factory settings but it did not help. Does anyone know what the issue could be? Could it be that my battery is dead/too weak? Any solutions? Advice? Any help is appreciated!!! Thanks.
