    I wouldn't say there's an actual proximity sensor per se, but RIM has built-in a new function that while on a call, while outputting through the small speaker, if there is a certain amount of contact with the screen, it will black out. It has to be a big enough area being touched in order to black out; it takes me 3 fingers on the surface of the screen to make the screen black out during a call.

    Note that this blackout feature isn't active while on speakerphone, since you're most likely actively navigating the phone if you're on speakerphone.

    Yup. It operates on the same principle as the setting on a laptop trackpad that allows it to differentiate between a finger dragging across it, and your palm. It uses the multitouch capabilities, if most of the screen has contact, the simulated "proximity sensor" kicks in.

    IMHO that they shoulda used the light sensor for the auto dim. when your on a call that sensor is covered and it should go black and lock. I try to keep my face away from the phone so it doesnt get oily and by doing that my screen doesnt go black. I have still had the issue where it either mutes or goes on speakerphone every once in a while. so screenlock has been my app of choice.
