I have noticed on my launch day 3G iPhone that my screen will like 'half' turn on at random times. My screen has like lines vertically down the entire thing, almost as if its half on. I dont know how to explain it any better than that, I'll try to get a pic. But when I press any button the screen turns on normally. Whenever my phone rumbles to tell me I have a new email it seems to do this or sometimes I will simply look at my iPhone before pressing a button to get to the unlock screen and it will be half on like this. Anyone else getting this? Is this a sign of any problems?
