At JailbreakingiOS6, we receive a countless number of questions pertaining to the jailbreak status of the iPhone 5, iPhone 4S, iPad 3, iPad 2, iPod touch 5th Gen and the UnTethered iOS 6 jailbreak in general. Unfortunately, the majority of your questions can be answered with one word, the answer is no. As of now, there isn’t an UnTethered jailbreak for 6.0 and the latest version of RedSn0w only supports the iPhone 4, 3GS and the iPod touch 4th Generation.
With that said, in this post, we’re going to discuss the major differences between UnTethered and Tethered jailbreaks and elaborate on the meaning of a Semi UnTethered or a Semi Tethered jailbreak.
UnTethered versus Tethered iOS 6 Jailbreak
Essentially, there’s only one noticeable difference to the everyday iOS-device owner between an UnTethered and a Tethered jailbreak. Without getting too technical, both jailbreak employ different forms of exploits, which result in a very different outcome. A Tethered jailbreak requires the user to rely on Redsn0w’s “Just boot” option in order to reboot their iDevice to its fully functional jailbroken state (we’ll discuss this further when reviewing what a Semi UnTethered jailbreak is). Alternatively, an UnTethered jailbreak doesn’t require a utility at all to reboot – hence the name “UnTethered”.
Also, I wanted to briefly elaborate on why Tethered jailbreaks only extend to specific devices and why UnTethered jailbreaks are so rare. As mentioned above, Tethered jailbreaks only include devices with an A4 processors or earlier, which would be the iPhone 4, iPhone 3GS and the 4th Generation iPod touch, as Apple has phased out the others. Moreover, newer devices with an A5, A5X or even the iPhone 5 with its A6 processor aren’t supported because Apple patched the limera1n exploit roughly two years ago, which is what Tethered jailbreaks are centered around.
While I could go on for hours explaining and thoroughly outlining the advantages, disadvantages and details of Tethered and UnTethered jailbreaks, I’m going to conclude this segment of the article by saying this: the Dev Teams are cautious. A lot of work goes towards the development of an UnTethered jailbreak utility and a lot of exploits are utilized. Once the UnTethered jailbreak is released, Apple can easily patch said exploits through an updated version of iOS, and so continues the game of cat and mouse.
Jailbreak iOS 6, Semi UnTethered and Semi Tethered
Semi UnTethered and Semi Tethered, what do they mean? Fortunately, we only have to explain what a Semi Tethered jailbreak is, as the two are one and the same. After performing a Tethered jailbreak through RedSnow, jailbreakers often prefer to install a package from Cydia that converts their Tethered jailbreak into a Semi Tethered jailbreak. While still required to reboot using RedSn0w to retain complete functionality, a Semi Tethered jailbreak allows users to reboot their device without the assistance of the utility for limited functionality. Essentially, the Semi Tethered package acts as a lifeline if you aren’t near a computer and your iPhone or iPod touch dies and you have to reboot.
