I'm confused (nothing new). My Apple TV2 is on v4.3 and it says it's up to date. Did you mean they released 4.4.1 and the pulled it and then re-released it again? In any case, my ATV2 thinks it's up to date.
Since the redsn0w "hack" talked about enabling AirPlay Mirroring (as well as gestures) for the iPad 1/Apple TV2, I'm wondering if mirroring will actually work with 4.4?
sorry, rushed when i entered that info, not far off though, i said 4.4.1, but here goes........they released 4.4(it is actually iOS 5 in our books), it was crashing/bricking apple tv's, so they pulled it, and later released a 4.4.1 which fixes that.

im guessing for airplay mirroring to work, you need to be updated.
