[*] shutdown the phone

[*]hold down volume up + power

[*]Now you are in the standard recovery mode

[*]assuming you have 2.3 SDK installed with fastboot (Google around for that info..), now on terminal/windows
or Windows cmd depending on OS type "fastboot devices" to check your device can be seem via USB

[*]assuming you device is seen via fastboot devices, now type "fastboot oem unlock"

[*]accept...and new bootloader is unlocked...

[*]now we need a custom recovery from clockworkmod or amon_ra, and we'll be good to go

Seems like a lot of people are having issues with the amd64 driver from the 2.3 SDK. Here's a workaround:

  • Go to the PdaNet homepage and download the Windows 7 x64 version of the PC software Download PdaNet
  • Make sure your phone is not connected to the computer. Install the app from PdaNet. Ignore the warning about HTC sync if you get it, that doesn't matter for what we're doing.
  • At the end of the PdaNet install, you'll be prompted to connect your phone. Make sure USB debugging is on, and connect to a high speed (as in not through a hub) USB port.
  • Follow the prompts and accept the unverified driver warning. Let it finish, then reboot your phone into fastboot mode -- power off, then hold volume UP and power.
  • Open the device manager in Windows (right click My Computer, properties, choose Device Manager from the list on the left.
  • Find the Android 1.0 entry, with the yellow exclamation mark beside it. Right click and choose to update the driver.
  • Select to search your computer for the driver manually, and point it at C:\Program Files (x86)\PdaNet for Android\. You will see a warning about an unknown/unsigned driver for sure this time, accept it.
When it finishes, at the command prompt (in the sdk\tools\ directory) type
Code: 
fastboot devices
you should now see your Nexus S listed.

You just unlocked the bootloader, this didn't root the device. You need to get a custom recovery

Technically, it's not rooted, but in essence, we all know that once the bootloader is unlocked, we can fastboot flash a custom recovery. And from there, we can flash custom roms or just the su and superuser.apk into the stock rom from recovery. So yea, it is kind of rooted.

    Using supercurio's root method I rooted my Nexus S then using ChainsDD's Superuser zip from http://xdaforums.com/showthread.php?t=682828
    I install su to /system/bin/su and Superuser.apk to /system/app
    (If doing this note you will need to "mount -o remount -w /system /system" and need to "chmod 4755 /system/bin/su" and you can copy files from your usb storage using "cat /sdcard/su > /system/bin/su")

    Then I rebooted to stock boot image and ran adb shell and ran su and was set, then I captured some images for you guys:
