I was just outside and I got a text message, and I was going to slide to unlock my iphone but it wouldn't let me slide. It ended up going to a blank screen and now it won't turn on at all. i've tried plugging it into the wall and my computer, it was completely full on batteries though after a full night's charge. Anyone have any idea on how to fix this? There's no apple store within 2 miles, I just started school again today, and really can't be without my phone.
