It means you free your iPod Touch from the restrictions and boundaries that Apple has put in place to prevent the installing of 3rd party packages and applications that are not hosted on the Apple App Store. In other words it allows you to get paid or free packages that are hosted on typically Cydia (TM) or Rock [Your Phone] (TM) that may not necessarily be present on the Apple App Store. This process has been an invaluable for users such as myself at getting certain utilities and "tweaks" for the iPod Touch that are yet to be released by Apple.

Jailbreaking iPhones can also be invaluable in the sense that it provides the potential to "unlock" the device meaning that other mobile carriers aside from AT&T can be used on it such as T-Mobile**

**Only mobile carriers on the same radio frequency as that of AT&T and T-Mobile will work; thus, this means that it is impossible to unlock the iPhone for Verizon and other such carriers at this time in the United States.
