The process allows for modifications to Apple’s mobile operating system, giving users increased control over their devices. It circumvents software restrictions imposed by Apple, enabling the installation of unauthorized apps, tweaks, and themes. For example, users could customize the interface beyond standard options or gain access to system-level settings normally inaccessible.
This practice is important because it provides users with the freedom to personalize their devices and potentially unlock functionality not officially supported. Historically, it has been a method for accessing features that eventually became integrated into standard iOS releases, and for extending the lifespan of older devices by bypassing software limitations. Concerns exist, however, regarding security vulnerabilities and warranty implications associated with such modifications.
