According to Pong Research, the 3G iPad has a proximity sensor which reduces the power of the 3G radio by up to 75% when the iPad is within 10mm “of the body.” “As a result,” the product page says, “all commercial cases for the iPad and iPad 2 also cause the proximity sensor to trigger, which can reduce your transmission power by up to 75%.”. All, that is, except the ones sold by Pong Research. The problem? Try as I might, I can't find a proximity sensor. The iPhone has one, which is how it knows to switch off the screen when you put it up to your face.
