The new year has come and gone, and the Epic 4G still doesn't have an official Froyo build from Samsung and Sprint. They tried to meet their goals, but things happen and at least Samsung has let us know they still want everyone to have a "simple/reliable upgrade". That's good news, because we want you guys to have a simple and reliable upgrade as well. But in the meantime, all who have turned to the dark side of root can take matter into their own hands. Epic 4G forums moderator ragnarox has taken the time to whip up a very comprehensive guide using some popular hacks that not only will get you your Froyo fix, but will put Samsung's rfs file system to bed and replace it with the much snappier, and more reliable ext4 file system.
Samsung keeps their phones pretty hacker-friendly, and with instructions this detailed it might just be time to give it a go. Hit the source link, have a read -- and ask ragnarox any questions you might have -- then decide for yourself if you're finished waiting. [Android Central's Epic 4G forums]
