HTC SDA (USA) / SP5m (Tornado)

Has anyone got the voice tag/dialing working? My experiance is that it randomly works. even after it finds the number by the voice tag it seams to not have any number to dial. on my bluetooth headset jabra BT200 I press the button on the headset speak the name.. the name is repeated over the BT headset.. then the call is on the handset.. did microsoft release WM5.0 to soon or did T-mobile screw up the software?
