What can a jailbroken iPod touch do?

A jailbroken iPod touch is basically like hacking it. You can personalize your homescreen with a wide selection of themes and you can also get apps that cost money for free by downloading a package from the software that automatically installs when you jailbreak your ipod touch. I have jailbroken my iPod touch and i ersonally think it looks much better than it was when i got it :P. If you have any questions or if you want me to give you the link to jailbreak your ipod and if you choose for me to send you the link i will tell you a step-by-step guide to getting the package for free apps and how to get themes just tell me :) !
