We've expanded on our first look at the Sprint HTC Touch Diamond to cover all the bases: phone reception, camera quality, TouchFLO 3D improvements, bugs, GPS and more. Verdict? We still like it a lot and it's definitely one of the best WinMo phones Sprint's ever offered.
By the way, I have this phone and the Jawbone II. Voice Command works fine from the Jawbone II. Completely hands free. Just press and hold the Noise Assassin button for about three seconds (while in stand-by) and Voice Command will activate (You'll hear it through the headset), then speak your command. I even got it to work while I was in a different room from the phone. The range is wonderful.
