I have had my Pro for less than a week, but had the Incredible for a few weeks and hated the all touch screen because I am coming from Blackberry Bold. I need buttons I've been reading the threads trying to pick up things here and there. Some of the "droid" terminology I am completely clueless to. Can someone please explain "root" to me and what it does? Are there different types or is it a one time thing you do to customize your phone even more? Also, it my understanding correct that once you "root" you void your warranty.
