Before the update, I could play/pause, skip, go back using the buttons on my Sony MW600 stereo Bluetooth receiver. Even worked on the HTC Music app (older versions of Sense such as on the orginal DInc did not support it.) Now the Rezound does not respond to the buttons in any music app. I wonder if this is a phone problem, an update bug, or an intentional crippling of ICS. Anyone else have or not have this problem?
