A5 Untethered Jailbreak details on Absinthe for iPhone 4S and iPad 2


It's virtually the tip of the week and Pod2g announcement on his weblog that the A5 untether jailbreak will A5 be launched in just a few hoursIt’s going to be from a brand new software referred to as Absinthe by means of the power Dev. 

The brand new jailbreak software has been developed via the Absinthe Cronic Dev Group and it installs the Untethered Jailbreak your software. The iPhone Dev Staff brings a CLI (command line) instrument to repair issues when issues go mistaken.



The Untethered Jailbreak for the A5 devices like the iPhone and iPad 4S twoapproaches. We are very excited about this like all the iPhone and iPad 4s 2 userson the Jailbreak wait. In our previous article we had on the status of the iPhone and iPad 4S 2 jailbreak that are in the final phase.


A tool named Absinthe and developped by the Chronic Dev Team will install the untether on your device. Also the iPhone Dev Team will release a CLI (command line) tool to help diagnose issues and repair things if it goes wrong.

Today the iPhone Dev Team wrote a new article entitled "Corona A5 jailbreak nearlyready to pop". This means that the Corona A5 Jailbreak almost ready to pop! In thismessage we see some important information about the long-awaited iPhone 4S and iPad 2 jailbreak.

It sounds a bit scary but the chance is very small that it goes wrong, by the Dev Team's many tests are performed on different devices. It is the first time that such a jailbreak method. The jailbreak uses the backup / restore function of iTunes to install the jailbreak.


Due to the combined efforts of @pod2g and members of the iPhone Dev Team and Chronic Dev Team, we’re nearly ready for a general release! All technical hurdles dealing with the underlying technique have been overcome, and its now all about making the jailbreak as bug free as possible…

Jailbreak programs:

To be as flexible as possible, the A5 version of the corona jailbreak will take multiple forms:

  • Chronic Dev have incorporated the overall flow into a GUI that runs on your Mac or PC. The goal is for the GUI to be enough for most cases.
  • iPhone Dev have incorporated the exact same flow into a command-line interface (CLI). This will allow us to help users through individual steps of the jailbreak manually, to both help the user and help improve the overall flow. Although the CLI will also allow the user to perform the entire jailbreak from beginning to end, we anticipate it will be more useful in debugging the occasional errors. The CLI currently has over 20 individual options (in addition to the single “jailbreak” option) that should be useful during debug after the GUI release.
  • Once all the bugs in the flow are worked out, we’ll also incorporate it into the redsn0w GUI (but still leave the CLI freely available too). In order to maximize the chances of the jailbreak working for everyone, the redsn0w GUI will use native Apple iTunes libraries — this technique is slightly different than how the Chronic Dev GUI handles communications, and should provide nice combined coverage for all the odd computer configurations out there.


The supported firmware versions will be:

  • iPhone 4S: 5.0 (9A334), 5.0.1 (9A405) and the “other” 5.0.1 (9A406)
  • iPad 2: 5.0.1 (9A405)

iPhone 4S owners looking to maximize their chances of achieving an eventual software-based carrier unlock should be staying at 5.0. Everyone else should be at 5.0.1. If you’re an iPhone 4S owner who already updated to 5.0.1, it’s too late to go back down to 5.0. But if you’re on 9A406 it is possible to downgrade the BB by going to the 9A405 version of 5.0.1 while the window is still open.

Note that they did not mention th erelease of GreenPois0n RC7.  Furthermore, the Dev Team warns that this style of jailbreaking has never been done, as usual, it is highly recommended to always use your device to give iTunes a backup
