Tethered Jailbreak vs. Untethered Jailbreak — What's the Difference?
By Tayyaba Rehman & Urooj Arif — Published on February 13, 2024
Tethered Jailbreak requires a computer to start the device each time it reboots, while Untethered Jailbreak allows the device to start up on its own.

Key Differences
Tethered Jailbreak means that each time the device restarts, it must be connected to a computer to enter the jailbroken state again. This process can be inconvenient because it requires access to the specific software used for jailbreaking every time the device reboots. Untethered Jailbreak, on the other hand, is much more user-friendly. Once applied, the device remains jailbroken even after it is rebooted, eliminating the need to reconnect to a computer.
Untethered Jailbreak is often preferred by the majority of users due to its convenience. Once the jailbreak process is completed, the device operates as if it were natively unlocked, with no further actions required from the user upon restart. Tethered Jailbreak, while less convenient, is sometimes the only option available for newer or less common firmware versions until an untethered solution is developed.
Security implications differ between Tethered Jailbreak and Untethered Jailbreak. A Tethered Jailbreak, requiring physical connection to a computer for reactivation, could be argued to offer a slight security advantage, as it adds a layer of complexity to unauthorized access. Untethered Jailbreaks, providing seamless usability, may pose a greater security risk since the device remains in a jailbroken state without needing physical tethering.
The development complexity and availability vary between Tethered Jailbreak and Untethered Jailbreak. Often, a tethered jailbreak will be released first, as it can be simpler to develop. Developers then work on converting this into an untethered jailbreak, which can take additional time and resources due to the complexity of bypassing the startup restrictions of the device.
Choosing between Tethered Jailbreak and Untethered Jailbreak depends on the user's needs. If immediate jailbreak access is needed and the user does not mind the inconvenience of tethering, a Tethered Jailbreak can be useful. However, for those seeking a more seamless experience, an Untethered Jailbreak is the superior choice, offering freedom from the computer and the ability to maintain the jailbroken state effortlessly.
