I recently updated to 2.0. I installed two apps and the next day the bottom half of the dock (bottom .5 inches of the screen) doesn't respond to touch anymore. So this causes several problems, it allows me to slide to unlock, but no access to dock buttons. I restored the phone, no luck. I called apple, of course the phone is 2 weeks out of warranty. I tried to restore to 1.1.4 but it doesn't work, I assume because of the new firmware apple installed with the update. The apple guy says it is a hardware issue, but I have a feeling it might work again with a downgrade. Any ideas?
