All you have do is;
1. Visit http://www.jailbreakme.com on your iPhone, iPad or iPod Touch.
There really is no step 2... that's all you need to do. The download/installation takes about 7-10 minutes, but it doesn't require you to do anything except wait for it to finish. It's being reported that this JB process works on every iPod Touch & every iPhone, across all OS versions, as well as the iPad. I can verify that it does work on the new iPhone 4, with the newest version of iOS 4.0.1 running on it.

Once the process is complete, you will have a new icon on your desktop, Cydia. Cydia is basically an App Store, but for jailbroken apps; created by people who didn't want to give Apple a % of sales via the iTunes store, or simply from people who's apps were rejected for one reason or another.
Now I'm off to download PDANET so I can teather my iPhone to my netbook... and not pay an extra $20 a month to AT&T
