If you want to tether your iPhone without jailbreaking then that’s also possible. Not exactly legal, but probably better than jailbreaking your handset.

First off you need to upgrade the OS to version 3.0 and then you will be able to start tethering in almost no time. This solution is said to work in any country, regardless of what carrier you’re working with. What you have to do is go to a certain site from your iPhone, help.benm.at, then download a file which will reconfigure your local carrier profile and the tether your phone as if you already have that option available.

The downsize of this procedure seems to be that it might disable MMS and/or voicemail. And it might also be detected by your favorite carrier, in which case you should expect some sort of slap on the wrist. Now that you’ve been warned, go ahead and do what you will to your iPhone!
