    1. Open Photobooth on your mac.
    2. Hold your iPhone 3G S facing the camera
    3. Bring up voice over.
    4. Look look above the screen on the iPhone.

    What the heck is that?

    That's the infrared transmitter for the proximity sensor. It's the same thing if you hold a remote control to a camera and press a button. It's visible to the camera but not the human eye.

    It does the same thing in a call, it's what detects your face to the phone.

    I think that is the sensor that shuts off your screen when you place the device up to your ear. I placed a call on the phone and put a finger in front of that area and it shut down the screen. IR sensor? That is what it looks like on the photo booth screen. Big Brother?:rolleyes:

    Edit: Looks like Ken was responding at the same time. He beat me to the punch, and a lot more eloquent.
