A new Android 2.2 Froyo build for the Nexus One, FRF91, has begun OTA distribution.  Landing on one of our own Nexus One handsets this morning, the update seems a relatively minor one and is only 2.2MB in size.

It’s been speculated that this could contain predominantly security fixes and tweaks from the previous FRF85 distribution, though so far there is no change log from Google that we can find. ¬†Anyone else out there finding FRF91 being offered for their Nexus Ones?
