However if you wish to see if it is already available you can do so by navigating to Settings > About Phone to trigger it. If this doesn't work then you can consider just uploading the ROM update to your Samsung Nexus S right now (instructions below via AndroidAndMe) instead of refreshing your About Phone screen throughout the day.
Grab the update file from Google; Place on the root of your SDcard; Power off your Nexus S, then once it’s off, hold volume up and power to boot into the bootloader; Navigate with the volume buttons to recovery, and use the power button to select it; You should see a warning triangle shortly after that, from there, hold down the power button and press volume up; Select apply update from /sdcard and choose the update file; Reboot your Nexus S with the menu option provided; and Enjoy!
