The well known iPhone developer and hacker Joshua Hill of the Chronic Dev Team has provided an ETA for the arrival of updated GreenPois0n jailbreak tool for the newly released iOS 4.2.1 firmware. For those of you who don’t know, GreenPois0n is based on Geohot’s Limera1n bootrom exploit which has already pwned all current iOS devices for life. The only problem is that it is a tethered jailbreak, which means you will have to boot it into a “jailbroken state” using a tool like Redsn0w on every reboot.

Chronic Dev Team have lived up to their promise! The source code for Limera1n-based GreenPois0n iOS 4.1 jailbreak tool is now available publicly for download. You can use the source code under the terms and conditions laid down by General Public License (GNU) to modify the tool to your own liking, or even improve it for the betterment of the jailbreaking community.

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.

Folks at Chronic Dev Team have released Linux version of GreenPois0n tool which like the Windows version can jailbreak iPhone 4, iPhone 3GS, iPod touch 4G / 3G and iPad on iOS 4.1 and iOS 3.2.2 respectively.

GreenPois0n is now available for download. If for some reason Limera1n didn’t work for you, you can give this one a try to jailbreak iOS 4.1 on iPhone 4, 3GS, iPod touch 4G / 3G and iPad. Support for iPod touch 2G and Apple TV will also be added soon.

GreenPois0n took weeks upon weeks upon weeks of development and hard work from the Chronic Dev Team. The SHAtter exploit based tool was supposed to release today, but after the release of George Hotz’ Limera1n (which is based on a new exploit; pwns all iOS 4.1 devices), Chronic Dev Team had to make a very tough decision.

This is just in. Members of Chronic Dev Team have confirmed that SHAtter based GreenPois0n jailbreak for A4 iOS based devices is finally dropping on 10th October 2010 at 10:10:10AM GMT. According to them, the said tool is done and is ready to release on the mentioned date and time.

iOS 4.1 Jailbreak news time! We have a lil’ update for all you guys anxiously waiting for SHAtter based GreenPois0n tool. Chronic Dev Team hacker p0sixninja, one of the hackers who are working on GreenPois0n jailbreak with SHAtter exploit, has tweeted that the tool is not coming out tomorrow or today or any fixed date for now.

With the low-level SHAtter exploit scheduled to pwn all iOS devices for life soon, it wouldn’t be wrong to say that the iOS 4.1 jailbreak will go down in history as one of the most anticipated jailbreak tool releases ever. And it is now “seems” only a matter of days, not weeks, till GreenPois0n tool is released.

In our earth-SHAttering honest efforts in bringing you the latest and greatest news from the world of jailbreaks and unlocks, we often publish posts that arise from simple tweets from some very important people. This is another one of those posts and it’s coming from none other than the Chronic Dev Team (the guys behind the upcoming GreenPois0n jailbreaking tool).

Vincent has just tweeted that the SHAtter exploit based jailbreak for iOS 4.1 for iPhone 4 / iPod touch 4 and iPad will be released soon. Why would we do an entire post after a simple tweet? Well, that’s because good ol’ Vincent here is the administrator of The iPhone Wiki (an encyclopedia which collects, stores and provides info on iPhone hacks), so the source is authentic and extremely reliable.

I don’t know whether to call it HUGE or what, pod2g – the person who found the SHAtter exploit and helped discover 24Kpwn – has announced that he is now leaving Chronic Dev Team in order to work independently.
