So my husbands iphone 4 just shut off today and will NOT turn back on..I've tried charging it, and nothing. We took it to the Verizon store and they couldn't turn it on..which means we couldn't transfer the phone numbers out of it to a new phone...and our icloud account wasn't working properly and now he has lost all his phone numbers...a few hundred between 2 businesses! IS there anything we can do??
