The practice of modifying the operating system of iOS devices to remove manufacturer restrictions enables the installation of software not authorized by Apple. This process, commonly referred to by a specific keyword phrase, allows users to gain elevated privileges. An example would be installing utilities that customize the user interface beyond the standard options provided or adding features that are otherwise unavailable.
Circumventing these limitations provides access to a broader range of applications and functionalities. Historically, this practice stemmed from a desire to personalize devices and utilize features not offered within the confines of the original operating system. The perceived advantages include enhanced customization, access to unsigned code, and the potential to bypass carrier restrictions.
