I also like the idea of using the click wheel to make a retro style digital-rotary phone. However, I doubt Apple would just display the numbers on the screen and not on the unit. So when in dial mode, you would spin the click wheel and the numbers, displayed on the display in a circle, would highlight the number that you were on and then click the center button on the click wheel to select. If you wanted to get really old school, you could have the rotary sounds come through the headphones. Or course you would still be able to dial by your address book or search through a downloaded version of the white or yellow pages (which would naturally sync into your phone whenever you charge it at home, via blue tooth or direct connection to your computer).
