Does anyone have a list of Cingular phones that work seamlessly with the A6 bluetooth?

As of last week when I bought mine, the T637 was only available via Cingular website. My cingular rep in Jacksonville, Florida said they did not carry anymore. I did buy through website and it works great with full functionality.

I have a Nokia 6820. Bluetooth connection is excellent. I can not, however, use the phonebook from the phone. The car recognizes and controls the phone but does not see the phonebook, last dialed, etc...

Anyone have a phone where its is fully integrated?<ul><li><a href="http://www.nokiausa.com/phones/6800">http://www.nokiausa.com/phones/6800</a</li></ul>
