iPhone developer Joshua Hill of the Chronic Dev Team has publicly confirmed that he is going to release an updated version of GreenPois0n with support for iOS 4.2.1 jailbreak as soon as he is done adding sandbox patches.
Yes you read that right ! An Italian site contacted Comex of Spirit and JailbreakMe fame to ask him about whether or not he is going to release his untethered jailbreak tool for iOS 4.2.1. Comex’s reply was swift and simple, à la Steve Jobs. He is going to wait for Apple to release the next firmware update to public before releasing his tool.
This is just to let you all know that we have now updated our previous article about the untethered iOS 4.2.1 jailbreak using Redsn0w 0.9.7 with a complete step by step video guide. You can follow the well explained instructions in the video to jailbreak your compatible iPhone, iPad or iPod touch on iOS 4.2.1 using the newly released Redsn0w 0.9.7 beta.
The Redsn0w 0.9.7 jailbreak tool has been updated yet again. This time fixing even more bugs, specifically the ones related to non-GUI programs which handles media content like the embedded videos in iTunes.
The iPhone Dev-Team have just released their “backup plan” (Redsn0w 0.9.7) for untethered iOS 4.2.1 jailbreak. The just released beta version of Redsn0w will enable you to jailbreak (untethered) iPhone, iPad and iPod touch on iOS 4.2.1.
Confirmed ! Redsn0w Untethered Jailbreak (Backup Plan) for iOS 4.2.1 Will Be Released On Christmas !
Since Comex’s untethered jailbreak for iOS 4.2.1 has been delayed, MuscleNerd of iPhone Dev-Team has announced that they are going to release their “backup plan” for untethered iOS 4.2.1 jailbreak over the Christmas weekend. However before they do a general release, they are looking for testers to try out this latest version of Redsn0w. The requirements for testing Redsn0w for iOS 4.2.1 untethered jailbreak are as follows.
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.
We have just been tipped off, by the user himself to an interesting story that he posted over at ModMyi Forums where he bought a new iPad (running iOS 4.2.1) for his lady as a Christmas present, only to find out that he was not able to jailbreak it using the latest version of Redsn0w.
We have already told you about an upcoming tool named Antid0te which promises to enhance the security mechanism of all the current jailbroken iOS devices so that they are secured as much, or even more than the non-jailbroken iOS devices. This new method uses ASLR (Address Space Layout Randomization) process which has been absent from all the current iOS devices, making them vulnerable to attacks such as the ones demonstrated at Pwn2Own contest.
Comex of Spirit and JailbreakMe fame has confirmed that a more efficient userland-based untethered jailbreak method for iOS 4.2.1 will be released before Christmas 2010. This confirmation in fact came before MuscleNerd got a backup method to make jailbreak untethered on iOS 4.2.1.
