Crossing the Blues
The differences between the original iPhone and the iPhone 3G are fairly modest. From a quick look at the front of both models side-by-side it would be unlikely that the casual observer would notice a difference -- each have an identical 3.5" display with 320x480 resolution at 163 ppi -- although the 3G model does have a slightly wider black frame around the screen.
