iPhone sensing

As I have mentioned elsewhere, I am thrilled by the fact that various sensing technologies are getting so cheap that they are incorporated everywhere. As could be seen from the presentation of Apple’s new iPhone, it includes an accelerometer to sense tilt of the device (and also movement if they decide to use that for anything), a proximity sensor (ultrasound?) to turn off the display when the phone is put to the ear and a light sensor to change the brightness of the screen (?).
