I am in an unusual circumstance for me. I cannot be very disappointed. In a rare turn of events, I held off on version 1 due largely to lack of 3G... I never expected it to take a full year to remedy that oversight. Also, I was starting new business and decided to keep using what was working well for a bit. I bought an iPod Touch to tide me over and have been using a Blackjack for a phone. Ha, Windows mobile operating systems blow. Battery life is criminal on the Blackjack, but at least i can swap out batteries. I cannot make it through a one active day on one battery.
I would be very happy if it was just the old iPhone with 3G and apps. I will buy it in a nano-second. GPS? I suppose I would prefer it has it, but not that much. Better camera? why not. To me... 3G is a must with a phone that has such nice internet and soon to be apps. If I could choose, the next most important addition after 3G and apps is video chat. It would be the communication device of sci fi movies of lore.
I still can't believe this thing has been running Edge all this time. Seriously, you can't do voice and data at the same time.... yeesh, 3G will be a huge improvement, even notwithstanding the huge increase in bandwidth.
