Oh, hmm, maybe I was wrong then - since I don't have Symbian60 I wasn't 
paying that much attention, but there certainly seemed to be a lot of 
discussion about it.

The P900 will let a computer (that's properly paired with it) to prod it 
over Bluetooth.  The P900 then makes a PPP connection back to an rfcomm 
emmulated serial port on the PC and you get a proper PPP connection 
between the phone itself (not the GPRS provider) and your PC.  Most 
applications are quite happy using this PPP connection for all internet 
access, although a couple of applications are nasty and insist on opening 
a GPRS connection instead.

The alternative is to use the Bluetooth "Cordless handset" profile, but 
that would require more software on both ends since neither Symbian, nor 
Asterisk support doing that ATM AFAIK.

I did play with getting my Bluetooth headset working with the (very alpha) 
ALSA bluetooth driver, but the driver just outputted noise to my headset 
for a few seconds before crashing the BlueZ stack on the PC.  There's lots 
of chatter on the BlueZ mailing lists about doing bluetooth headset 
support but noone seems to be actually _doing_ anything about it. :)
(I for one don't have anywhere near the experience with Bluetooth and ALSA 
to work out how to do it myself).
