I too bought the iPhone (JB/Unlocked 16G) to convince myself there was something better than a BB. However I was wrong. The iPhone does have a better web experience but it lacks in too many ways to compare it to a BB. Now I have a $500.00 video player on my hands, which I do use to watch movies and listen to music while I actually get things done on my 8320.
However the end result is within yourself and what uses you intend the iPhone to satisfy.
If you can't do it on one wheel, try harder!
