how to connect to 3 mobile net work in the U.K with the N800
 

I have a motorola V3x which hooks up to the N800 via bluetooth as it should, i can transfer data from the phone to the N800 i.e. photo files. I have a data package from 3 mobile in England to go on to the internet. I would like to hook up the phone to down load maemo mapper routes and the like when out, away from wi-fi. I have tried to use the connection set up wizard on the N800, I have set it up to send packet data ( if thats right ), but am lost at the point where you enter a dial-up number, username and password.

If any of you know which way to make this work I could spend more time on something else, thank you
