[BTM] phone with full address book

[R.Hannes Niedner]

I am looking for a phone that allows me to sync the complete address 
book entries and not just the phone numbers, but I am not interested in 
getting a full blown PDA or Sony EriccsonP800/900. I got a Cingular 
contract and from what I have read on Apples iSync site the Nokia 6620 
is not yet supported. I would be grateful for any suggestions or 
experiences.
I have the SE T616 which is ok but doesn't offer a full (sync-able) 
address book. I would love to have a clamshell phone but from what I 
found googling Motorola phones are supposed to have a crappy OS 
(especially the address book) whilst the SE Z600 doesn't offer a full 
address book.
