Ever since Android 2.2 was made official at Google I/O this year, Android fans have been anxiously waiting for the offical Froyo update to roll out.  If the folks over at Sizzled Core are to be believed, Google has finally flipped the switch.  Sizzled Core posted a photo today of a Nexus One running a higher Android build number, FRF72, than what everyone else with Froyo has, FRF50.  FRF50 is the unofficial version of Android 2.2 that Google leaked recently.  The FRF72 update is reportedly only 1.8 MB in size, with the only updates meant for the browser.  Some users over at xda-developers claim that this shot could be easily faked, but those that believe it's real point to a tweet from a Google employee who received a Froyo update today.  Considering that Google officially unveiled Froyo almost a month ago at their Google I/O event, it makes sense that they would finally be pushing the update out.  If this is indeed fake, though, there will be some frustrated Android fans left wondering when the update will actually come.  What do you think?  Is the FRF72 build the real deal?
