While we're still waiting for an official Froyo build to be released for the AT&T Samsung Captivate there is now a few leaked ROM's floating around. If you all remember when UCJI6 leaked back in October 2010, it required some ODIN hackery to get it up and running. A new leak has now popped up -- I897UCKB1 is available for anyone on the adventurous side just remember, experimental builds can cause some chaos so be proceed with caution. File in question can be found at the source link, and you'll need ODIN again to get it going. [XDA] Thanks, Conan!
Update: We've got video of the leaked update after the break.
