Even though I wasn't supposed to be able to upgrade until December, I got a text this week about being able to upgrade now. I went into the store to play with the Thunderbolt and the thing sure is pretty. I was wondering from others who went from the original Droid to this phone how steep the learning curve was? Anything you miss about the old phone (besides the keyboard, obviously). Also, I've done some poking around about rooting it (gotta have wifi tether). I was able to root the Droid but by the time I had done it the community had it so well fleshed out that a 2-year old could have done it. Is it easy to root the Thunderbolt or do you need a degree from MIT? Any thoughts are appreciated.
