Okay so in August the OTA update was sent to my phone. I downloaded it, and hit the restart to install. My phone restarted and nothing happened. So my phone is still running 4.0.4. I can't get another update until this one occurs, and it's not happening. It's been 3 month or so since that day and i really want that update. I don't want to root my phone, and i'd like to maybe have some kind of means to fix it by maybe sending an email to google or something.
Model: Nexus S
Baseband verion: I1920AUCKJ1
Build Number: IMM76M

any help is welcomed!
