The listing, Iphone 4 (Malfunctioning) has ended.
I have an iphone 4 that will not stay powered on. I bought it off of a friend and the restore function in itunes gives me an error code (21). It powers up to the apple logo and itunes plug in screen as if it is ready to be set up, but it powers off as soon as you unplug it. It may be fixable, it may only be good for parts, but it is a very nice phone. No physical damage. Barely a scratch. This is an AT&T phone.
