I don't know if anyone else is having this problem, but occasionally the screen will go dark and be unresponsive to any commands. I have found this to be most common when i come out of a call. I currently have a milestone screen protector on it, so the proximity sensor doesn't work, but still the power button doesn't wake the screen. I have found the only way to get it to come back besides a battery pull would be to plug it in. I don't know if there is any more information needed, but i figured i would point this issue out now and see if i am not the only one with this.
