MyDroidWorld founder p3droid is reporting that he has obtained an official Google update of Android 2.2 dubbed FRF84B. The version proximity to the Nexus One’s official Froyo update (FRF85B) is certainly uncanny. Based on the large file size, it appears to be a full ROM. Unfortunately, no official Google link for the client is available, only p3droid’s rooted (read: now technically unofficial) version. The update comes with superuser permissions for root only apps, as well. It is available for download below.

Certainly, someone has obtained a potential Droid Froyo release candidate from Google, that much seems safe to assume. The big question, though, is whether or not this update can be installed straight from Eclair 2.1 Droids. It appears that this is indeed the case; users on the MyDroidWorld forum have indicated a successful update is possible from a rooted ESE81 or other rooted Eclair 2.1 version with a non-stock recovery image, but may require a factory reset in order to work properly.

Be forewarned: users on the forum are reporting minor issues (such as problems with the Market and some apps) upon install. General install instructions and additional download links below:

To update to the official (leaked of course) release version of Froyo (Android 2.2) for the Droid follow the directions below.
