No, it is not enough for me to want to upgrade. I will hold out and see if we get a new hardware revision this year. Honestly (and let the flaming begin), aesthetically, I prefer the 1st gen iPhone to the 3G. I like the shape of the back much better, and I know this is a completely crazy thing to notice, but the black housing area around the screen on the 3G is a lot wider than the 1st gen, and for some reason, that bothers me like nails on a chalkboard. I see it like buying a flat panel TV with iether a huge black frame around it, or a very thin less noticeable one. Everyone wants the less noticeable one, and imo, the 3G having that extra space around the sides of the screen makes it look cheaper. Add to that I really don't care about GPS features and while 3G is definately nicer than Edge, it was not a big enough reason to buy the 3G before my 2 years were up on the 1st gen. If by September, they have new hardware, I am upgrading definately, if not, then I will still probably go to 3G then.
