Is there anything that is impossible or undoable for the developers/hackers? I bet not! Give them anything new and the first thing they would want to do is modify or alter it to be in total command. Nexus S is no exception and some of those smart folks have already Rooted the Nexus S on Gingerbread.
In case you aren’t aware, Rooting your Android based device lets you play around and overclock your CPU, flash desired ROMS, get rid of the lousy Carrier loaded apps, etc. I did that on my HTC Desire and it looks better now and even more smarter folks have done this with the latest, Nexus S.
The picture on the top is a proof to what I state and has been done. It shows the Nexus S running a custom Clockworkmod recovery and he has been kind enough to share the same. For those of you who have the heart to try the steps out feel free to follow the steps below at your own risk:
First, reboot into your bootloader/fastboot mode. (Volume + Power Up, or adb reboot bootloader)
fastboot oem unlock
Then, install this recovery:
fastboot flash recovery recovery-clockwork-herring.img
Then boot into Clockwork recovery and install the Superuser zip file (adb reboot recovery, or from fastboot choose recovery):
To install a rooted/insecure boot image (adb has root, THIS IS OPTIONAL, THE ABOVE STEPS ALREADY GOT YOU ROOT):
ROM Manager support is in the making and will be available soon.
