LG Optimus Q - Screen Frozen

view story

http://forums.androidcentral.com – UGH!!! Out of the blue my LG Optimus Q's screen is frozen. It won't allow my to taptouch at all. I am able to get around a little using the keyboard (thank heaven for a slide out keyboard here) but I can't make calls to anyone unless I have a txt msg saved from them. I've tried removing the battery and rebooting, no luck. Screen is still frozen!! Any advice would really be helpful here. :'( (HowTos)
