So i would search for what I'm trying to ask here, but I honestly have no idea what to look for. Do I need to "root" my phone to get custom themes? I've been seeing some really cool screen shots of these X's with custom themes and I want to do this too, but I have no idea where to begin. Does rooting your phone involve breaking "certain rules"? Does rooting my phone have risks that I should be concerned about? And what are ROM's? I see that everywhere i read about themes too. Can anyone help out a noob? Any help is much appreciated.
