Video shows dueling early iPhone prototypes


A video by a supply chain rumor source known as Sonny Dickson shows two early original iPhone prototypes. One appears to be basically a multi-touch port of the iPod click-wheel user interface and another a wireframe of icon/button touch interface.

I'm not sure how much can be drawn from there. I'd guess this may be where Apple was testing concepts and perhaps we can see some iteration of what an all-glass front would work rather than the then conventional physical keyboard.
