The process under discussion involves modifying the operating system of Apple mobile devices to remove restrictions imposed by the manufacturer. This modification, historically facilitated by a particular software tool, allows users to gain elevated privileges and install applications not authorized by the official app store.
This practice offers users greater control over their devices, enabling customization options and the ability to utilize unofficial applications. This once provided access to features before their official implementation, and bypassed restrictions on software distribution, contributing significantly to the early mobile software ecosystem and user empowerment.
