Sorry I didn't see there's already another thread about this, please delete this one. I'm stuck at work right now, so...for those who were able to upgrade to iOS 4.1, how is your experience with Bluetooth headset(s)? Are the next/prev buttons working properly? Will the volume buttons finally be controlling iPhone volume like they did on other phones? Can it display the name of the song current playing on your headset's LCD screen? Were you able to access call records and contacts properly on your headset LCD screen? If so, were you able to make a call from the contact list with your headset buttons? P.S. In case you're wondering, I didn't make up these functions, I've got a Sony Ericsson HBH-DS980 stereo headset, and all of the above functions work on a SE phone.
