iOS hacker iH8sn0w has discovered a way to untether jailbreak devices powered by the Apple A5(X) processor for life, which includes the iPhone 4s, iPod touch 5, the iPad 2 / 3 and iPad mini. Details are relatively scarce at this moment regarding the iBoot exploit, although if the exploits were ever bound together and released in the form of a jailbreak utility, those in ownership of either device would be able to enjoy an potentially indefinite, untethered jailbreak.
The iPhone developer and hacker iH8sn0w has just teased a screenshot of Sn0wbreeze 2.2 with a new “Baseband Preservation Mode”. This new mode will enable current iPhone 4, 3GS and 3G users to preserve their baseband while upgrading to iOS 4.2.1 so that they can unlock using existing version of Ultrasn0w.
Just like Chronic Dev Team’s GreenPois0n, the Windows counterpart of PwnageTool 4.1 known as Sn0wbreeze 2.1 has been fully open sourced and it’s source code is available to public for free. What’s the point of making it open source? You can modify the tool according to your own liking or even improve it for the betterment of the jailbreaking community under the terms and conditions laid down by General Public License (GNU).
Sn0wbreeze 1.7 for 4.0 (for Windows) has been released. This release supports iPhone 3GS (old and new bootrom), iPhone 3GS, iPod touch 2G (MC and non-MC models), and iPod touch 3G. Though iPhone 3GS (new bootrom), iPod touch 2G (MC models) and iPod touch 3G will have to be either on 3.1.2 firmware, or will need to have their SHSH blobs saved for iOS 3.1.2 in order to successfully jailbreak these devices on iOS 4. Also the jailbreak for iPhone 3GS (new bootrom), iPod touch 2G (MC models) and iPod touch 3G on iOS 4 will be tethered, which means whenever you turn off your phone, you will need to re-connect it to a computer to be able to turn it back on.
Ok guys.. Mac version of the guide is now up! (Windows version can be found here) The requirements though as mentioned earlier remains the same. You will need a iPhone 3GS (with new bootrom) on iOS 4, which has SHSH blobs saved for iPhone 3.1.2. Some other important notes about the jailbreak are as follows.
There is a new video going around in the wild which shows iPhone 3GS (with new bootrom) on iOS 4 jaibroken using an upcoming version of Sn0wbreeze. This video has been confirmed by iH8sn0w - the developer behind popular iPhone jailbreak tools such as sn0wbreeze for iPhone 3.1.3 / 4.0, f0recast and BlackBreeze as legit.
