My Iphone 4 will not work unless I have it plugged into the wall. I unplug it or try to plug it into the computer, it will not work. any suggestions?
Have you left it plugged in to its charger long enough to charge the battery?
You probably have a bad battery. Try a different cable to see if you can get it to accept a charge. if you can't then take it to an Apple store for a new battery.
