Jailbreaking an iOS-based iPhone has taken the Apple owners by storm since last year. With every new refresh of iOS that is pushed out by Apple from time to time, different jailbreaking teams are ready to jailbreak it and are offering it to fans who have grown accustomed to using a jailbroken device.
For those who are new to the jailbreaking front, iOS jailbreaking is the process of eliminating the limitations forced by Apple on devices running the iOS operating system through the use of software exploits. These devices include the iPhone, iPod touch, iPad, and second generation Apple TV.
What this process does is that it allows iOS users to gain root access to the operating system, allowing them to download additional applications, extensions, and themes that are unavailable through the official Apple App Store. No wonder it may seem like an exciting prospect for all Apple users, whether old or a new Apple owner.
Those who are in touch with the jailbreaking process are currently waiting for the highly anticipated untethered jailbreak for iOS 6 and iOS 6.0.1. However, with numerous fake claims about a successful jailbreak by self-proclaimed jailbreakers over the last couple of months, users have found it difficult to distinguish the genuine from the phony ones that do not work.
Several different types of jailbreaks exist – tethered jailbreak, untethered jailbreak, and semi tethered jailbreak.
A tethered jailbreak is one where if the device starts back up on its own, it will no longer have a patched kernel, and it may also get stuck in a partially started state. For it to start completely and with a patched kernel, it essentially must be "re-jailbroken" with a computer. That can be done using the "boot tethered" feature of a jailbreaking tool each time it is turned on.
An untethered jailbreak, on the other hand, has the property that if the user turns the device off and back on the device will start up completely and the kernel will be patched without the help of a computer. Simply, it will be jailbroken after each reboot.
A semi tethered jailbreak, however, means that when the device starts up on its own, it will no longer possess a patched kernel, and will not be able to run modified code. However, it will still be usable for normal functions.
Those who are waiting for an untethered jailbreak for iOS 6 and iOS 6.0.1, the truth is there are no such jailbreaks as of now. Although the jailbreaking teams are working hard to find a solution, there is still some time left before a final jailbreak arrives.
iPhone Dev-Team member @planetbeing, about 3 weeks ago, tweeted a photo of the iPhone 5 running the IntelliScreenX Cydia tweak. Since then, there has been nothing from him on the anticipated jailbreak.
Another renowned iOS hacker Joshua Hill, aka @p0sixninja, is also reportedly working on getting the encryption codes for iBoot that could help dumping the bootROM. A bootROM dump would, sequentially, make untethered jailbreaks for future iOS devices much easier to achieve.
However, on Friday, Nov. 30., a video (see below) of the full hour-long talk was uploaded on YouTube that explained some important points regarding the much-awaited untethered jailbreak. There is it was stated that Apple had patched up the security in iOS 6 that made it very difficult for jailbreakers to write kernel exploits, but @pod2g and @planetbeing had divided the work among themselves and, currently, while @planetbeing is working the kernel exploits, @pod2g is working on finding a userland exploit, trying to find a vulnerability to trigger the code execution.
Nonetheless, users of iOS devices running iOS 6 or beyond are recommended to stay away from the fake jailbreak Web sites that claim to provide iOS 6 and iOS 6.0.1 untethered jailbreak. When a real working untethered jailbreak arrives, it will be notified by the team.
