I just read a review of Droid 2 on PCMag.com. In the section about phone features and performance they wrote, "Very annoyingly, the Droid 2 screwed up Bluetooth voice dialing support. While you can trigger voice dialing over a Bluetooth headset, you can't issue the commands over the headset, eliminating the point of the exercise."
Uh-oh! Is this true? The state I live in becomes totally hands-free behind the wheel October 1, so it is vital that voice commands work through a car speakerphone and/or headset.
