Woke up two days ago and screen on my 3Gs was just milky white and was unresponsive to any input. Rebooted, all good. Today, my home screen rendered and then was not able to "slide to unlock" or anything else for that matter. Reboot, fine. Either of these two things and the remedy is no biggie, what worries me is the proximity of these two events to each other. Is my screen slowly deteriorating? Did I get a lemon? How long do I have before I can justify a swap if problems persist? I bought the phone June 24th...or in that vacanity. Thanks..
