This refers to modifications made to the iOS operating system, specifically version 16, without requiring full “root” access to the device. This contrasts with traditional jailbreaking methods that bypass system-level security to grant extensive control. Functionally, this allows for customization of the user interface, addition of features, and alteration of system behavior, though with limitations compared to full jailbreaks.
The significance of this approach lies in its enhanced safety profile. By operating within a more restricted environment, it reduces the risk of introducing instability or security vulnerabilities to the operating system. Historically, full jailbreaks presented trade-offs between extensive modification capabilities and potential risks to device security and software updates. This method aims to mitigate these risks while still offering a degree of user customization.
