The big things are 3G support and GPS. Functionally you can get the 2.0 software for the original iPhone. Small changes to the cabinet (rounded edges on the back and black or white plastic back instead of metal. For some (me included) the sq is slightly better on the new. On the new the touch screen and the glass front are seperate so cheaper to replace if the glass cracks. The battery is not soldered but is still not user replaceable in the practical sense of the term.
