    i was just looking at the tech specs of the iphone 4 and noticed something odd

    Sensors:
    3-axis gyro
    Accelerometer
    Proximity sensor
    Ambient light sensor

    what does it mean my 'Proximity sensor'??
    it knows when your near it or something?

    The proximity sensor IS that grill over the earpiece on the white model (it's there on the black too, just not as visible). It detects when your face is next to the phone and turns the display off, to save battery life and keep you from doing random **** with your cheek.
