Here are a few (very blurry) images of my iPod touch running 3rd party applications. The jailbreak process was very easy using this guide from TouchDev. It does require a bit of command line work so I’d recommend waiting if you’re uncomfortable with the command line. Several “one click” applications are now popping up, but I can vouch for any of them considering I haven’t tried them. Here is a Mac “one click” application called iJailbreak and a Windows “one click” application called TouchFree.
