Stop the presses! Untethered Jailbreak for version 4.4.4 (iOS 5) is out! I’m working on mine, will have a full guide up!
So, I discovered it works the same way as previous guides, just make sure you update your Apple T.V 2 to version 4.4.4 by connecting it to iTunes and clicking restore (even if you are currently Jailbroken) and then follow the steps in my original guide. Found here!
As always, xtechs has a video up super quick, however, I would recommend the guide above to use, and if you are confused, check out xtechs video for clarification.
