Connect phone to Telstra NextG using Ubuntu?

[Jean Hollis Weber]

Hello,
I have a Nokia 6120classic, a NextG account with Telstra, an internet 
account with iinet, and Bluetooth on both my computer and the phone. At 
home I have ADSL (so I don't need the phone to connect) but when travelling 
in the outback I used to access the internet using a CDMA phone as a modem 
(with a serial connection) and iinet's dial-up number. Now I want to use my 
Nokia phone as a dial-up modem with the Bluetooth connection.

I run Ubuntu 7.10. All the posts I've found on the Whirlpool site about the 
Nokia6120 not surprisingly say "It's easy, just use the PC suite software" 
which of course is Windows only. Not much help!

Can anyone help me? (Can it be done?) Note: I can use a command line and 
edit config files if I have to, but otherwise I am really a dummy when it 
comes to a lot of this stuff, so if someone could explain in really simple 
terms to me what I need to do, I would be very grateful. Thanks!
