Whoa.. halt.. stop. Beeeeeeepppppp!
I suggest you learn rooting and its pros and cons before ever ever learning how to.... don't bake a cake unless you know how to use the oven!
Search android central.. tons of "what is rooting" articles.. Google search too.... and obviously, there really the articles about how to root the DROID RAZR .... but like the cake, you can follow the recipe but if you don't know the oven, then you can ruin the cake and maybe even the oven... we all had to learn this way...
Rooting bypasses the manufacturers and carriers lock on the phone, thus granting you only 1 thing... admin super user access to Android... it install 1 app only---super user. All of your mods and advanced customization comes from rooted apps, like titanium backup and set CPU and ad-free and etc.. how you work the apps is your own doing. Like setting the oven temperature. Mess with it the wrong way, and you'll turn the cake (phone) into a useless brick.
So again, read and read read read. Google search. YouTube. AndroidCentral... learn learn and relearn. Read and read and reread. Dont just jump into the recipe cause everyone else is doing it.
I'm not trying to be mean.... just honest. To many times I have read these forum threads and article comments and even people on my own Facebook page stating "oh I just got the phone last week and tried to root it so i can ovwrclock it or remove all ads on all apps and now the phobe don't work. I hate android!".... 1--don't blame android from bricking a phone over your quick judgements and maybe not reading all instructions properly. 2--know what your doing before ever doing it.
Welcome to Android and I wish you luck on your future endeavors. And some advice. . once you learned rooting and rooting apps, you will forever learn... new phones pop up. New OS versions. New apps.. the learning never ends..
