i-book and nokia 6230 as modem

[hjp]

Anyone got any tips for how to use my nokia 6230 (with bluetooth, in UK) as a modem for my G4 i-book. I have tried to set it up unsucessfully for 2 nights in a row and am now getting frustrated!! I have bluetooth built in. Are the OS X settings as easy as it seems (ie. my phone settings are wrong) or is there something I'm missing? I notice you can download modem drivers for Windows OX on the nokia web-site but no mention of Mac.

Any tips / help would be much appreciated. Ta
