Jailbreaking gives iPhone users almost unfettered access to their devices, offering a slew of customizations, new features, and improved apps that you just can't get elsewise. Unfortunately, Apple has clamped down hard on the latest iterations of iOS, making jailbreaking extremely unstable at best. Hope is not lost, however, as there's still a way to install modded and unofficial apps on your iPhone, iPad, or iPod touch without any jailbreak.
