I've been reading a lot of posts and around the net (not just here) that say that the iPhone 3G is not a significant upgrade. Everyone is saying how dissapointed they are that there is not much that is new. My belief is that people think the 3G is not a significant upgrade just because it looks the same. If you think about it, everyone went crazy for the 3G when it was released, but really the only major differences were 3G, A-GPS, the casing, and maybe even the headphone jack. Now, the 3G is released with a faster processor, more RAM, better camera, voice-control, etc. and everyone is writing it off just because it looks the same. What are your thoughts?
