In just 5 minutes I was able to set up my MacBook Pro to use my Sony Ericsson M600i as a blue-tooth modem. Here's how I did it:
These instructions are taken from Ross Barkman's web-site
http://www.taniwha.org.uk/. Even though the example below is for the SonyEricsson M600i, Ross provides 3G modem scripts for most handset makes. I have successfully used Ross scripts to set up networking with my SonyEricsson M600i as well as with my Nokia N70 and N80. Ross' scripts are pintware so please send Ross a small donation such as $5 for his excellent work.
Ross also provides local operator settings which you need in order to configure Internet Connect. For example, in the case of the Swedish operator Telia you enter the following:
Telephone Number: online.telia.se
User: guest
Password: guest
For all other operators, please see:

2. Set up PPP:
A. Open Network Preferences

H. Make sure that 'Send PPP echo packets' is not selected
3. Set up modem
A. Select the Bluetooth Modem (or the equivalent USB or IrDA name) tab in Network Preferences

4. If using IrDA, turn on Sony Ericsson Infrared port:

B. Line up phone's IR port facing IR port on PowerBook.
5. Connect:
A. Open Internet Connect
B. Select Bluetooth Modem Port (or the equivalent USB or IrDA port name)
