What's the deal with the Ambient Light Sensor or ALS on the iPod touch. If you Google "iPod Touch Ambient Light Sensor", the first couple of Apple links say about the sensor. Then when you click on the page you cant find it anywhere. Its like they have changed it. I have always noticed that the ALS doesn't seem to work on the iPod. I'm sure theres one there as I can see a tiny dark black dot above the display. Can anyone tell me what the score is? Thanks. Alex.
