For those who have already updgraded to AppleTV 4.4. Seas0npass is still working, it just downgrades to 4.3. I did it just now Oct 16 2011 12:54pm Australia EST. It did take me ages as I kept getting error 1600, 20 etc. When I eventually got it working I had put it into DFU mode before running seas0npass. Only had USB cable plugged in and did it by pressing down + menu until it does a fast flash, then pressing menu + play/pause till it does a fast flash. Then run seas0npass and follow directions.
