No, it's not free. It cost $20 from Planetweb when they were selling it. They discontinued it at the end of this past year though. You could try emailing them to see if they'll still sell you one, but it's probably a long shot.
You can find them on ebay for more than I'm willing to pay, but in many ways, you're better off with 2.6 anyway. 3.0 is nice, but it crashes a lot. And for the trouble you'd have to go through at this point to get one, I'd say use 2.6.
People have tried ripping it, but it's to big to fit on a CD. I don't know of anyone who has succeeded yet.
This is also an issue where I say if you want it, and can get it from a legit seller, you should buy it anyway.
I hope we've been helpful.
