[Help] Galaxy Nexus - still no 4.2 update

Hi guys!

So, I got a Galaxy Nexus early last month. Here in Brazil it's called "Galaxy X" for copyright issues. It's not yakju/takju, so I rooted, unlocked and flashed the yakju 4.1.2 image. Everything went fine, but I have a problem now: I still haven't received the 4.2 update. I left the phone unlocked and have the stock recover. Am I missing something (it's my first Android phone, had iPhones for 3 years before).

Thank you.
