My touchscreen just stopped responding yesterday. No impact or any other event to seem to trigger this, I was talking on the phone then put it down after the convo, then a few seconds later I tried to unlock it and it wouldn't respond to any touch at all. And since I have no idea how to unlock the phone using the physical keyboard I can't get to anything. I rooted it months ago only to do tethering, but I haven't installed any custom ROMs or anything yet. Does anyone have any suggestions? Do I need to do anything to it if I end up sending it it to Verizon? Thanks!
