We have some good news for the entire iPhone jailbreak community. The popular iPhone hacker and an iPhone security specialist have posted a YouTube video to demonstrate his new untethered jailbreak method to jailbreak iOS 4.3.1 on iPhone, iPad, and iPod Touch.
Esser posted a YouTube video on his account to showcase his untethered iOS 4.3.1 jailbreak running on his iPod touch 4G. If you are unaware, an untethered jailbreak method is a jailbreak which allows you to restart your iOS device without need to re-jailbreak it. At the moment, you will be able to jailbreak iOS 4.3.1 using PwnageTool and Sn0wbreeze, however, both jailbreak tools is offering tethered jailbreak only.
Now, Esser – also known as i0nic - has announced that he already handed the iOS 4.3.1 untethered jailbreak exploit to iPhone Dev Team for beta testing. Fortunately, the undisclosed jailbreak exploit found in iOS 4.3 remains unpatched in the latest iOS 4.3.1 release. Here are some of the iOS devices that can be jailbroken on iOS 4.3.1 using this undisclosed exploit:
• iPhone 4
• iPhone 3GS
• iPhone 3G
• iPod Touch 4G
• iPod Touch 3G
• iPod Touch 2G
• iPad 1
The only iOS device which can not be jailbroken is the recently released iPad 2. Furthermore, Esser has provided more details about his untethered jailbreak solution:
Meanwhile everyone should have noticed that my prediction became true and Apple released iOS 4.3.1 in order to fix the PWN2OWN vulnerability in Safari.
It was very unlikely that Apple also fixed the kernel vulnerability I used for my untether exploit. Mainly because the kernelcache binary is about 8-10 MB in size and the likelihood that Apple finds the same vulnerability in that short amount of time was very low.
However you never know until you try it. So this morning when I woke up and saw that Sn0wbreeze 2.4 beta was released I thought it would be fun to create a new video.
Unfortunately Sn0wbreeze does not work with my iPad 1 and so I had to test with my iPod 4G.
In the video you can see how I switch off the iPod, then restart it, show the version, show that it is tethered and has the multitasking gestures, i show that you can buy ringtones and then I show cydia and the ninja jump game from last time.
Because several people misunderstood me in the past:
a. I repeatedly stated that I will not release a jailbreak tool – I will only give out the untether. I did not try yet, but if it is feasible the untether could be a cydia package.
b. While the vulnerability I use is in the iPad 2 kernel my untether will NOT SUPPORT the iPad 2, because there is no way to install it there (bootrom exploits fixed). – however Comex is working on that part.
c. I am not giving out any ETA again, because the Jailbreak community is simply nuts. Last time I gave an ETA and even before that had passed I got constantly insulted by people that were demanding an immediate release. Sorry guys the more you insult people with the knowledge to actually do what YOU WANT the less motivation there is to use our free time to give it to you.
d. The only reason why I did not finish the untether before the ETA was due to unexpected work overload in my real job. It had nothing todo with the untether being too hard or unreal.
e. I don’t know why the dev team has not released a redsn0w that does tethered jailbreak for 4.3.1 – I would prefer that to be available, cause sn0wbreeze obviously does not work 100% yet.
f. If you want to learn more about iPhone kernel hacking/exploitation you should come to SyScan Singapore at the end of April.http://syscan.org/index.php/sg/program
