I have an iPod Touch (1st Generation) running 2.2.1. But enough techno-garble, my question is much more general. I mainly use my iPod for music. Duh. Occasionally I have photos or a movie on it, but for the most part it is a music device. Why would I want to "jailbreak" it? What the heck is a jailbreak, anyway? Is it useful enough for an average Joe like me... or is it for little boys and girls who want the new blah blah blarg marf? What do you use your jailbreak for?
