I have a Nokia 6230, so may be the same. In the phone under connectivity settings under GPRS setting, under Edit Active Access Point, under GPRS Access Point, change to wap.cingular That is the only change I did to my phone.
The rest of the info I needed I found here

Its pretty easy just pair the 2 devices together for blutooth,
then on the pda under settings then under connection tab
you can use the connection wizard to help you thru the rest.
I had mine up and running in less than 1/2 hr, I just cant remember
the specifics but I hope my response helps a little.
