WOW! Voice dialing over Bluetooth? For reals?

But seriously - any idea if it's speaker-independent type or you have to train it? I would love to switch back to BB for this but I don't want to lose any features.

I'm currently using a Cingular 8125 (WM5 device) and it's OK - still miss BB - but I can't live without MS Voice Command now. It's so much fun seeing how long you can go without having to touch your phone
