One of the biggest thorns in Android's side so far has been lack of Bluetooth voice dialing. (These are phones, after all.) For those of you on-the-go who need to safely use the phone features without touching it you now have the option in Android 2.2.
Once your device is paired and connected, a press of the action key brings up what you see above. You're greeted by a female robotic voice who also repeats your instructions. Seems fairly accurate (as accurate as my Blackberry or Pre), and worked well with both a Motorola MOTOROKR S305 set and a Jawbone Icon in my testing. Shout out Froyo-ers -- does your headset work, and how's your Bluetooth experience on 2.2?
