iPhone 3GS will not take charge,shows usb plug interesting?
I have a real problem. Phone started to shut down randomly and would not take a charge and shows plug symbol(usb). I have changed charger, battery(correct for 3gs) and charge port. I have updated etc via Itunes. still no joy phone works fine on new battery until power drops out. Do you think this is terminal and a motherboard failure?
Is this a good question?
