Root Your Nexus S
“The Nexus S has only been out for a few hours and already it has been rooted by XDA member Koush. The process is pretty quick and simple to do if you’re savvy enough and have rooted a device before or have experience in ADB. It doesn’t require much to root it, just a few files and some ADB wizardy.
So, if you want to go and root your brand new Nexus S then check out the Discussion Thread, also dont forget to hit the thanks button if you appreciate the work Koush has done!”
