volume on the iphone does nothing. my sony DR-BT22 headphones have volume control for the headset.. works brilliantly.
play/pause working perfectly, no track skip yet.
I find that it really only skips for me if I start going something else (like play a game) and then go back to the ipod.. and try to listen music with the unit sleeping.
If I wake it up, stop the track, start it playing again and then sleep it, it doesn't skip.
About the same as beta 2
