Help can't update to 2.3.5

[acithium]

I've got a nexus s i9020 stuck at version 2.3.4. I know that 2.3.5 is out and maybe 2.3.6, but for some reason they haven't come to my phone yet. Were these updates only for the 4g version, or is there some issue that I'm not aware of?

2.3.5 is for 4g, you can have it with custom rom, 2.3.6 is for Google voice bug and stop tethering.
