I like getting a notification (in the form of a sound or vibration) when I receive a new text message. But I don't like that the screen turns itself on. I am new to the iPhone (just arrived after 5 years with Windows Mobile), but I am surprised that there is (apparently) no way to keep the screen from coming on automatically? I worry that the screen will turn on while the iPhone is in my case, while I'm driving for instance, and I'm not sure at what point the screen will turn itself off (I don't know what constitutes enough activity/movement in the case for the screen to think it's in use).
