And now it’s comfirmed.
The FroYo (Android 2.2) update for Nexus One that’s been running wild online is not a final version. There are no worries for all of you that have already done the manual update, you’ll get the OTA when it’s released. Quote below from “passion-ate” in the official Google Help Forum, also confirmed by “Ry-Guy” by his best answer selection, both are Google Employees working with the mobile team. Link at the bottom:
“Hi all,
Thanks for the responses!
Just wanted to give a heads up that the build floating around is not the official Froyo release. You will get an automatic notification when we OTA the build, no need to manually download it. You will still get the automatic notification if the official release is a newer version than the one you have, so don’t sweat…but I’d highly recommend waiting for our official release :)
We are striving hard to OTA the build to you ASAP, thanks for your patience!
Gaurav”

Good news for everyone worrying bout some odd behaviours from the new build and new features not working exactly like expected!
