Also I have noticed that when I am using my bluetooth headphones when it is on the speaker dock I can now have the audio go straight to my headphones and not from the speaker dock itself. That's the way it should be because before it would only play from the speakers when it was docked regardless if bluetooth was connected or not, it would ignore it and just kick it out. This is a nice fix for me personally because maybe I don't want the sound to only come from the speakers if it was docked.
Everything new in 3.1 rocks but everyone before me pretty much listed it all so that's it from me.
