Bluetooth Internet Setup

I don't know if this has been posted before or not, but I have a slight problem on my hands.

I've been trying and trying again to get Internet setup through Bluetooth from my phone to the laptop. I have a Sony Ericsson Xperia X10 and a 2010 MacBook Pro.

Any tips?

Assuming your phone supports Bluetooth tethering and your carrier provides the service, the details should be covered in your manual (they're usually device-specific). Barring that, you might want to have a look over on Howardforums, which specializes in cell phones.
