Funny enough, it was the Moment's bug where proximity sensor doesn't always work as it should when you are too quick (but now I've mastered it and like it), which made me realize the Hero required pushing a button or using a hackneyed light sensor program to get the same effect. Seems strange it's lacking... almost as strange as a sub 640x480 record a/v resolution; that one I will never understand in a Fall 2009 phone.
