Well, the first thing you should probably think about is what are you going to do, or what are you trying to do, or why are you rooting your Razr. Not trying to be a smart ass, but rooting your phone does absolutely nothing...it won't work faster, it won't get better battery life, it won't look different...rooting simply does nothing in and of itself. Rooting only gives you access (usually via an app or utility) to system settings that you typically do not have without root which in turn enables you to run apps that MIGHT improve phone performance, better battery life, flash ROMs and themes etc. There is a sticky above which provides a utility that you can use to root your Razr. I recommend that you have some idea of what you want to accomplish with root before you do it, otherwise you are taking an action that could cause you warranty problems, prevents you from receiving OTA updates unless you unroot and really has no benefit by itself.
