For what it's worth I just thought I'd share my experience. I got a Motorola RAZR v3 Black last night (Cingular). Awesome phone. I can synch it up to Mac OS X 10.4.7 without any problems, pairs just fine. Can synch contacts with Address Book in about 5 to 7 seconds, can drag and drop pictures, etc. It's cool to see your Mac show "Motorola RAZR" on the "discovered" Bluetooth devices and on the phone it shows "Anthony's Mac Mini"
