On the arm list, a couple of people said that OpenBSD probably wouldn't be able to use a CF card to do bluetooth GPRS with a bluetooth phone.
Here's the most interesting response I got:
"AFAIK, looking into src/sys/netbt, it seems that BT support in OBSD
is far from complete. Only HCI commands/events are supported, L2CAP and
RFCOMM is not implemented. The particular driver support (BCSP in the
case of Socket Communications (rev G) bluetooth card) wouldn't really
matter until network protocol stack is completed."

Seems like even a bluetooth USB dongle would be pointless. Any ideas? I used to use GPRS with my T610 phone with my C860 (cacko rom) and it was pretty useful. I'm trying to figure out if I can duplicate the experience somehow on a C3100 running OpenBSD.
