I have the iPhone 3g, but I really really like the physical form of the 2g. I am sure I could find someone either on the forums here, or online who would willingly trade phones with me. But what would I be losing? I use the gps function sometimes, but printing out google maps before I leave my dorm isn't the worst thing in the world. So what else? Is there anyone who has had both that can compare them a little? Also is the data plan cheaper? Thanks guys!
