Hello, just purchased a Samsung F300 and planned to use it as an EDGE modem with the 770. Piring and the Modem function with the previous phone I had (W610) was with no problem, but in case of the F300 although the pairing seems to be ok, when trying to establish a connection, it just ends with an error without even sending or receiving a byte or so.
The thing is, that when when in pairing mode, the phone tries all the time to retrieve the list
of provided services from the 770, but of course it ends up with sthng like "no available services from this device". And then the BT sign on the display of the phone, next to the 770 is not blue as in case of another machines paired with the phone, but providing some filesharing or other BT services.

Pls. if anybody have an idea, how to establish a connection, pls let me know,
I am using the connection tutorial on the 770, after pairing (which is maybe not finished),
and then using a service type that used to work with my previous phone. Thnx, mrn

ok. problem solved.
for your interest: i needed to to add "receive-all" into "/etc/ppp/options"
on the 770. ciao! mrn
