What is rooting? Why should I root ?
By default your Nexus S phone comes with default users and many system functionality and parts of the operating systems are not available with these users. Rooting procedure creates a SuperUser which can be used to access privileged parts of the operating system. Many applications such as ScreenShot app requires you to have root privileges. You can also install custom software like MiUI and latest builds of android if you have a unlocked rooted phone.
There are 2 steps in rooting:
