Android 2.2 Froyo for the Nexus One -- FRF72 -- is very real. It finally leaked in the past few hours, we've tested it on a Nexus One of our own, and as far as we can tell, it's straight-up legit. Get it if you dare -- it's up on Google's official servers right now, but if it's pulled, we've no doubt it'll be floating around on a bunch of mirrors ad nauseam. G'luck to ya, folks!
