An even easier to use GUI version of planetbeing’s 1-click iPod touch Jailbreak application has been released depreciating most of my previous guide. The new version requires fewer reboots and installs the alpha version of Summerboard but still installs an old version of Installer.app that you will need to upgrade. Portions of the guide that are still relevant can be found below.

You can download the new version and get instructions on how to use it here.

Final Steps for Safety

It is a very good idea to change the default password from “alpine” to something else. This prevents people who happen to see your iPod touch on a wireless network from logging into it and doing nasty things. To do this:

1. Install “Community Sources”, “BSD Subsystem” and “Term-vt100″ packages from Installer.app.
2. Launch Term-vt100.
3. At the # prompt, type “passwd” (without the quotes) and press return.
4. Enter your new password and confirm it.
5. DON’T LOSE YOUR NEW PASSWORD! :) If you do, in order to log into your touch from SSH or SFTP you will have to do a restore and start this process all over again.
