I have an Apple PowerBook G4 laptop computer. I connected my computer wirelessly via Bluetooth to my Ericsson T39m world-wide GSM phone. And I used the phone as a modem to connect to a dial-up ISP.

So there you go.
It's a great convienient setup, since I can connect wirelessly to the internet from anywhere my mobile phone has service...even from onboard a plane (whilst it's on the ground, of course).
Not to mention that it's a heck of a lot less expensive than the Verizon airfone, especially with the number of mobile phone minutes I have.
