Hey all. So I am thinking it is time to upgrade to GB seeing as how our update has been pushed back to an unforeseen date. I know nothing about rooting though and am fairly terrified to destroy my phone. I had previously installed z4root which worked fine and i used it to rename some .apk in the startup. While i am confident in my ability to follow a guide, I guess i am just overwhelmed with the number of different roms. 1. How do you decide which one to choose? 2. If a rom doesn't work out for you, how difficult is it to switch? 3. do you need to completely wipe the phone again?
