so ive been highly contemplating rooting my phone...but i have some questions. does it change the UI at all? does it wipe away apps that i have? (for example..i have handcent sms, and a few messages i do not want to loose...will i loose them?) do i have to reinstall any purchased apps? is there anything you have to do to "upkeep" a rooted phone vs unrooted? thats all i can think of right now. thanks in advance for the answers!
