pretty much any bluetooth enabled phone should be able to do what you 
want. i personally prefer ericsson (now sony ericsson) phones. i've 
upgraded from t68m to t630 and k700i. i've also tried nokia phones (6820 
and 6600), but i did not like them that much :)

there are couple ways.

1) you could use serial port profile and standard AT commands set 
(gammu, gnokii). this should work with many phones. this way is 
typically used with nokia phones.

2) use OBEX/IRMC protocol. obexapp(1) from FreeBSD ports collection will 
allow you to pull entire phone books/calendar/etc. from the phone.

> serial port sync protocol.  PAN is the bt protocol to surf the web and

what do you mean by surfing the web?

if you would like to use your phone as wireless modem to connect to the 
internet then you need to use DUN. you also need to have GPRS service on 
your phone and have "internet plan" with your provider. typically 
providers will give you WAP over GPRS access and that does not work 
unless you have WAP stack.

if you actually want to surf web on your phone and use your pc as 
gateway/access point then you need LAN profile (PAN would also work in 
this case but FreeBSD does not support PAN).

> obex or something is for sending files?  Is this correct and what do

OBEX is a generic protocol to transfer files. yes.

> most phones usually support?

i'd say you are likely to get

Serial port, FAX, DUN, Handsfree, Headset, OBEX push, OBEX File 
Transfer, OBEX/IrMC
