My iPhone shut off and won't turn back on or charge. Help?
My phone abrupty shut off last night. If I recall correctly, it was at about 20% battery power. After shut off, I plugged it into my MacBook Pro to charge. Not only was there no charge, but my computer didn't recognize it as there. I tried holdng the Home button and the On/Home button together, but so far, nothing. I also restarted my computer with the phone still plugged in and it still didn't recognize. Any advise?
