It was initially expected that the untethered iOS 4.2.1 jailbreak might be released somewhere around the Christmas Eve. But if this latest tweet by Comex is anything to go by, we may not see an untethered jailbreak for iOS 4.2.1 by this Christmas.
The SHAtter bootrom exploit which was saved at the last minute because of Geohot’s Limera1n for the next-gen iOS devices such as iPad 2 and iPhone 5 has been leaked.
Earlier this month, Comex of Spirit and JailbreakMe fame confirmed that a more efficient userland-based untethered jailbreak method for iOS 4.2.1 will be released before Christmas 2010.
The most vocal member of the iPhone Dev Team, MuscleNerd, has confirmed that the much awaited unlock for iPhone 3GS & 3G (all basebands) on iOS 4.2.1 will be released this Sunday with a new Ultrasn0w update!
The iPhone Dev Team has just released an updated version 0.9.6b2 of Redsn0w which is based on Geohot’s limera1n exploit and it can jailbreak iOS 4.1 on iPhone 4, iPhone 3GS, iPhone 3G, iPad (on iOS 3.2.2) and iPod touch 4G / 3G / 2G (Non MC Model only). Besides, this new version also offers custom boot land recovery logos for the older devices like iPhone 3GS (old bootrom) iPod touch 2G (Non MC), and iPhone 3G, along with the ability to let Windows users restore to a custom IPSW files that are cooked using PwnageTool for Mac.
Both the iPhone and Chronic Dev Teams have confirmed that their respective jailbreaking tools, Redsn0w and GreenPois0n are going open source, which means that the entire source code of the mentioned tools will be available to public for free. You can then use the source code to modify the tool to your own liking, or even improve it for the betterment of the jailbreaking community.
Redsn0w 0.9.6 is now available for Windows. You can use it to jailbreak iPhone 3G and iPod touch 2G on iOS 4.1. If your iPhone 3G relies on Ultrasn0w unlock, stay away from Redsn0w as it updates your baseband to the latest version, making it impossible (for now) to unlock.
After showing off the demo of SHAtter exploit in action on an iPod touch 4G, the iPhone Dev-Team has now managed to jailbreak the newly released 2nd-gen Apple TV, running iOS 4.1 using SHAtter exploit loaded on PwnageTool. For those of you who don’t know, SHAtter is a low-level bootrom exploit which Apple will not be able to patch with a new firmware. Instead, they will have to introduce a revised hardware for all the current iOS devices to close the loophole. What this means is that once this jailbreak is out, all current iOS based devices will be pwned for life!
The iPhone Dev-Team has finally shown off a video demo of iOS 4.1 jailbreak on the newly released iPod touch 4G by loading SHAtter exploit in PwnageTool (video after the break). This test version of PwnageTool however is currently for internal testing only. But it will be released later for iPhone 4 users so that they can preserve their old baseband in future for carrier unlock by restoring to the custom firmware file.
Even though the newly released Redsn0w 0.9.6b1 officially supports iOS 4.1 and iOS 4.0 only, but MuscleNerd of iPhone Dev-Team has confirmed that iOS 4.2 Beta can also be jailbroken (on iPhone 3G and iPod touch 2G only) using this release of Redsn0w but don’t expect everything to work flawlessly.
