Everything works. Actually everything has been working forever. But I just set up aTV Flash Black on a friends ATV2 and noticed that his home screen has the snazzy looking buttons, and mine looks like the older home screen with the column style menus.
It’s showing that I’m on ATV Flash (black) 2.4 , and ATV 4.4.4 (3330)
I wouldn’t even care about it, but it seems the one drawback is my iPhone will stream fine on his, but not on mine.
