hello everybody. i have an iphone 3g that had the yellow screen of death. i tried many things but its completley unresponsive and itunes wont even read it. I left it plugged in over night and now it seems to be stuck at the apple boot logo. (i have no idea how that happened). Anyway its stuck at the boot logo now and its been so for atleast a couple of hours. I tried putting it into dfu mode, turning it off, nothing works and its completley unresponsive. anybody have any ideas?
