What does it mean to Jail break my iPhone/iPod Touch?
Jailbreaking is a term for modifying an iPhone/iPod Touch to run third-party applications. With a name like “jailbreaking” you’d think you were doing something wrong, but thankfully for all of us, jailbreaking is completely legal. And it’s awesome. Out of the box, there are many areas of your iPhone that are inaccessible to you. Jailbreaking frees these systems and unleashes your iPhone’s full potential!
