I've been using the phone most of the day, took a nap and now it won't boot. I always leave it on and it was charging when I napped for like 4 hours. The backup battery is fully charged at it doesn't work either. All I'm getting is black. Nothing when I hook it up to my laptop as well. I don't have a way of calling Verizon, as I don't have a home phone. I'm stranded. Please help! Thanks
