My iPhone 4s won't charge or turn on?
I've had my iPhone 4s for almost a year now,
but only in the past few weeks has it failed to charge. For a while, it only charged when it was switched off, which was annoying, but at least it was charging. Now nothing works. My phone only shows the red battery sign when I try to switch it on, indicating it needs to be charged. This is while it's plugged in also. I tried to contact apple but to do so requires a serial number. I have no way of finding out my serial number as it won't switch on, iTunes doesn't recognize that it's plugged in and because i purchased it from Amazon.co.uk, it uses a GPP card, so doesn't have a serial number on the tray. I'm completely lost with this one. Any ideas?
