IPod touch Jailbreakme.com site help, just shows a picture?

The mobile website just had a picture of some guy in the snow and a tree with a sign that reads "PDF". I just learned how easy it is to jailbreak using the site without the need of using a computer or downloading a bunch of stuff onto your computer, but now it won't work. Any alternatives to jailbreaking on just your device? Or how to get past this picture? I have the iPod touch 4 running 4.2.1
