The question is by whom. Apple? The sensor manufacturer? Nokia 7650?  
Some 3rd party?

See here: http://www.infosyncworld.com/reviews/n/2088.html

"On the upper part of the front, there's a proximity sensor for  
switching the loudspeaker function off when the 7650 is lifted to the  
ear, and a light sensor if the phone is set to automatically adjust  
the backlight corresponding to the lighting conditions." The article  
is from 2002 - oops - and I thought the iPhone is 5 years ahead?
