Since it seems like people are really interested in this information (especially those out side of the US where updates are not pushed out), I will continue with the updates regarding the Nexus S. Here’s the next (no pun) operating system update: 2.3.4:
a14a2dd09749.signed-soju-GRJ22-from-GRI40.a14a2dd0.zip (md5: 92b0f0a0b57a7cf10d2d70610c8bb9fb)
Again, this is directly from google (it is even linked to google), and you should follow the 7 steps from the http://blog.vpetkov.net/2011/03/11/google-nexus-s-update-manually-to-2-3-1-2-3-2-and-2-3-3/ article.
Please note that the update WILL work if you are running “GRI40” (build number in Settings -> About Phone)
The biggest update when it comes to new features seems to be that Google Talk has voice chat! There are a lot of bug fixes.

IF YOU GET AN ERROR:
Please just grab the FULL 2.3.3 (f182cf141e6a.signed-soju-ota-102588.f182cf14.zip) system, install it and then try again. It will work!
IF YOU JUST WANT THE RADIO UPDATE:
XXKD1-GRJ22-radio-nexuss-unsigned.zip (md5: 57659f04148ebfa849ef523544f2a3dd)
Note: I personally couldn’t update just the radio update from 2.3.3 (with GRI40) – kept getting the status 7 signature verification, so I used the 2.3.4 update to get the radio patches. I’ve seen people who have been able to apply the radio update to 2.3.3 without any problems.
