I searched around but had no luck finding info on this....is there a way to keep the screen from going black while the phone is charging? When I have it in my car, I keep it plugged into the cigarette lighter and use it to play mp3's. It's annoying to have to hit the power button and then slide to unlock every time I want to change tracks or whatever. I'd rather have the screen remain active while it's plugged in. I'm guessing that it will remain active if I get a car dock for it, but in the meantime...is there a setting that will let me keep the display active?
