Using a Mobile Phone as a Modem
A friend of mine just bought a new iBook G4 with Bluetooth and has been wanting to use her Bluetooth cell phone to act as a modem so she can get internet access. I myself have never set something like this up, so a quick Google turned up this website which really has a wonderful guide on how it all works. It has step-by-step instructions and pictures too!
I think my next cell phone is definitely going to be a Bluetooth one so I can get some internet access on the road!
