Yes but the BT Dialer that is now on 2.2 is a true BT dialer. Now when I push the button on my headset I get a voice through the headset that asks me to "Speak now". I'll then say "call Joe at work". The voice repeats the command back and then dials. The old activation of the Voice Dialer required you to touch the screen to confirm the dialing. I found too that the using the speakerphone to dial was often unreliable. Especially when the phone is a short distance away from you, i.e. the dash, and there was background noise present.
I much prefer the 2.2 version for BT dialing. It's still not without it's quirks at times but more often than not it works much better. Just my opinion.
