I am reading into the different roms and trying to figure everything out for the first time.. I understand that first i must root my phone in order to get any of them to work.. I also see that there is a way to back everything up so that you can switch back if necessary.. I really have 2 questions.. Which roms seems to be the best in everyones opinion? and the other is, so we first back up the phone and then root? or so we root and then back up?
