I upgraded to 3.0 and while it doesn't feel that big of an upgrade, I really do like some of the new features it has mainly copy and paste and landscape typing which I think were implemented perfectly. What I don't understand is why when you know that Apple knows about the jailbreak community they didn't implement some of the best apps that people want (boss-mods) or at least make a way to easily switch 3G or wifi on or off without having to go three menus deep. I guess what I'm saying is until they jailbreak 3.0 what features do you miss the most or are suprised you don't miss.
