Android Police report that according to Google the official final release of Froyo isn't too far off - following a recent build that appeared out of Google - FRF72, the latest known official build.
With the release of the new iPhone today, and iOS over the last few days, it seems as if Android users are getting a little jealous, with well over 1400 posts as of writing to a semi-official thread over on the Official Google Android Support Forums, and a Google employee dropped in with a short update on the status of the update:
Just dropping in to let you know that the FRF72 build that is floating around is not the official update. The Android team is feverishly working to get a final version out the door, but like passion-ate has mentioned this will only happen once a release candidate meets our quality criteria.
Since today is the Summer Solstice, we know things will be heating up a bit so hopefully Froyo will be on its way shortly. Thanks for your continued patience
Users also noted in the comments that another Google Employee said something similar way back on June 6:
Apologies for keeping everybody waiting. We are not intentionally holding back on Froyo, just improving the overall experience and quality. I don't have an exact date to share yet, but we are striving hard to OTA it ASAP. Stay tuned! - Gaurav
Currently there is no official date for Froyo's release, but many users are hoping it will be released by the end of June. Froyo is Android 2.2 under the hood, and sports a huge performance increase, full flash support, built in Wifi Tethering and more. You can find out more over at the Google Android developers portal.
