iPhone 3G won't charge with either the usb cable or wall charger.
Hi guys. got an old iphone 3g. Battery went empty. Doing the power and home button reset won't work. It won't charge anymore using either the usb cable or the wall charger. How do I revive the battery manually? I found a couple of hints online about manually removing the battery from the phone. Then using an old usb cable (red and black wires and hook it up on the battery. Is that a good idea or not? If it's a good idea, how do I know where the positive and negative terminals are on the iphone 3g battery?
Is this a good question?
