if anyone wants to update their nexus one manually, here is the official FRG83 from FRF91 update http://android.clients.google.com/packages/passion/signed-passion-FRG83-from-FRF91.c8847c98.zip
so this is what i found out about this update so far...
i havent flashed it but i did take it apart. this is what i found inside. has anyone that has updated this notice anything different in their stock recovery?
I have not tried to update either, however, many over on XDA that are rooted are not able to update. They are getting errors, those who have been able to are saying they see no difference.
I didn't even know one was coming, but I received mine around 3:30 am today. So far I don't notice much of a difference other than my downloads for Audible are much faster.
FYI, I posted some instructions for applying the update to a stock (but rooted) firmware while keeping root: http://kenkinder.com/2010/10/05/update-your-rooted-nexus-one-from-frf91-android-2-2froyo-to-frg83-2-2-1/
