Jailbreaking was created to break free of Apple's restrictions. They make sure you cant install third party applications, only the ones that they approve. Jailbreaking allows you to install other applications that aren't in the App Store. For example, an installable third-party app called Winterboard allows you to customize every aspect of your iPod. From status bar themes, to app icons, to lockscreen, to complete GUI overhauls.
Jailbreaking is also possible on Android devices, through the more commonly known term of "rooting" your phone. Similar to jailbreaking an iDevice, rooting allows you to break free of restrictions and customize almost anything and everything about your device, similar to Winterboard on iOS, as well as give you "root" permissions for apps which allows you to have even more functionality.
