Got a call from my daughter away at college tonight and she says the power button on the iphone 5 she received this past Christmas no longer works, luckily it's stuck in the on position! Any thoughts or idea's in fixing it? I had bought the phone from Verizon but I'm not sure if she needs to take it back to a Verizon store or an Apple store. It's only 2 months or so old. Thanks for any help.
