Hmm, interesting... Just tried it with a regular stereo headset, which shouldn't be any different from a bluetooth dog tag (A2DP/AVRCP). The good thing is that when Nokia's wired headphones get connected, the audio switches from bluetooth to wired and most of the control buttons from the BT headset still work! The bad news is that pause button for some reason pauses the progress bar in the media player, but not the actual playback... So, only prev/next work for me.
