Lady at the post office has an original iPhone she wanted me to look at. I told her I would try and figure this thing out, but don't think I will have much luck. It doesn't power on, on it's on. When you plug it in, or hook up to pc, the screen will flash from nothing on it(as it looks when it's off), to a light black(not fully powered black, like the start-up screen, but barely showing). It flashes over and over, and then it will start flashing to the start-up screen, then back off and on again. I've tried hooking it up to iTunes and no luck. Tried putting it in DFU mode, but it won't because it keeps flashing. Any ideas what could be wrong, and is it worth the fix? I was hoping to get it working for the free data thing, and then give it back to her.
