Android 2.2 (Froyo) leaked out for the Sprint Epic 4G and Samsung Vibrant on Saturday, amid much drama and the usual in-fighting. If you're like me and try to avoid that sort of thing, you're in luck as we're gonna break it down right here.
Froyo for the Sprint Epic 4G was leaked to a very select group of people. These folks are all in agreement about one thing -- it's far from ready for release, even to other hackers. The build has problems with the phone radio, isn't stable, and releasing it would be a big mistake. Nothing has been released for the Epic 4G to my knowledge.
Froyo for the Samsung Vibrant also leaked out to a few developers. This one seems pretty stable, and two custom ROMs are already available (here, and here). We also have word that support for the Vibrant in CyanogenMod 6.x will be much easier just by having this leak. The leak itself has not been made available.
We're going to bypass the feuding about open source, the GPL, and donation wars. If you feel the need to get into the mix and speak your mind, the usual channels is where you'll find the bickering. [XDA Developers Vibrant and Epic 4G forums, Android Central Forums, and Twitter]
