I have a week 37 touch and I got it the day my best buy got them in. It does have the neagative screen issue but this is not the problem It has been working fine for the last two months but all of a sudden today it is not responding. When I put it to sleep and then wake it up it will let me "slide to unlock" and maybe press an icon but after that...its done its not responding to any of my touches. Its really bugging me. Sometimes it will let me touch and click something but not very often. What do you think I should do? I don't have a warranty and the 30 day one is up. Would best buy do an exchange? ANY help would be greatly appreciated! Thanks!
