I was digging around some of the developer applications on my MacBook Pro.  I opened the Bluetooth Explorer.app and started playing.  I clicked Devices->Show Device Discovery and highlighted my iPhone.  While reading the Service Attributes, I noticed two “expected” attributes and two “unexpected” attributes.  The two expected attributes were Handsfree Gateway and Headset Gateway.  I have no questions with those two.  The two attributes that I have questions about are Phonebook and IrMC Sync.  Do these seem to be associated with the ability to sync the iPhone?  I think so!  I am very interested in this feature as I have also listed that as a feature request on iPhoneBugList.com.  My Treo 650 did it with no problems.  I would expect my Apple phone can speak to my Apple computers!

Below is the output from the Bluetooth Explorer:
