Froyo builds for the American Galaxy S variants, but they seem to be getting close. How close? Well, close enough so that you can taste a leak for the Epic 4G if you like to live dangerously. The binary comes conveniently pre-rooted by the source and has a handful of known issues -- most notably some sluggish / buggy web browsing -- but we guess that's the price you pay for stepping out on the bleeding edge. Let's hope an official release isn't too far behind.
