    From the iPhone Dev Team site

    Ever since the December release of @pod2g’s “corona” untether for iOS 5.x on A4 and earlier devices, all eyes have been on the attempts to extend it to the A5 devices: the iPhone4S and iPad2. 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 it’s now all about making the jailbreak as bug free as possible.

    On his blog, @pod2g playfully nicknamed the combined effort a “dream team”. It’s an ironic name, because the past few weeks have left everyone involved with very little sleep and the opportunity to dream :) But we’re now near the final stages of testing the public version of the jailbreak. Please allow time to clean up any remaining bugs in the jailbreak clients.

    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 also incorporated the exact same flow into an alternative 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.

    Paypal Contributions:

    Because there were so many different people and teams involved in the A5 corona release, we all felt the most equitable approach to any Paypal contributions should involve a single shared account. If you do feel the desire to contribute to the “dream team” Paypal account, it will be distributed to the members according to internally agreed-upon proportions :) (Please refer to this blog post for that specific link, to avoid frauds!) The same link will be on both the Chronic Dev and iPhone Dev versions of the GUI. This method seemed like the fairest to everyone involved!


    The supported firmware versions will be:

    iPhone4S: 5.0 (9A334), 5.0.1 (9A405) and the “other” 5.0.1 (9A406)
    iPad2: 5.0.1 (9A405)

    iPhone4S 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 iPhone4S 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.


    The overall flow used by the GUI and CLI to inject the A5 corona jailbreak has never been done before, and there may be unforeseen problems once it’s released to the public. It’s very important for you to sync your data, photos, and music before attempting any version of this jailbreak. We’ll be watching the comments section below for signs of any widespread problems, but please be aware that you jailbreak at your own risk!


    As mentioned at the start of this post: when testing has shown most of the bugs have been fixed!

    Oh, goody, another thread about the pending jb. Goody, goody, goody. You can never have too many threads on the same topic.

    Whose fault is that? There was also a new thread every time pod2g tweeted until someone made a thread just about his tweets. No one really has the right to complain. If it was really that big of a deal the mods would consolidate the threads or lock them.

    Based on the title of the main tread right now "pod2g updates blog" or whatever, I think this particular news is worthy of a new post. This is pretty huge news since it's on the dev team blog.

    I agree 100%. I am looking forward to all the new threads when the A5 jb is actually announced. So many to choose from and follow.:)

    Agreed. They also clarified things like who to donate to if you would like to and posting this to that thread might mean not everyone will see that and other details.

    When it's released, the mods will have to play clean up by deleting and closing the billion "omg, it's released" threads.

    I'm curious about the command-line tool they're talking about. It sounds like this may be a more complicated injection path that they are not sure will work consistently. Clearly the Dev-Team is not confident enough in it to build it into their flagship Redsn0w tool yet. My guess is that there is some tension between Chronic-Dev/pod2g who want a more immediate release and the more cautious Dev-Team which wants to perfect the jailbreak before releasing. Dev-Team usually doesn't deal in half-steps, so I'm thinking they've been forced by the need to coordinate with others to find a compromise solution.

    Great news and worthy of a thread, no matter who doesn't like it.

    I donated $10, but I feel like that's either not enough, or too much. It's always awkward giving to these kinds of things. I try to ask myself, "If this were a pricetag for the software, rather than a donation, what would I pay?"

    How do you guys determine a donation?

    It's a donation. There is no determination.

    Donate $1 or donate $100. Whatever you feel like.

    Or, donate nothing at all and just give them thanks and praise.

    I'm thinking (or hoping) it's more to do with them both wanting to take credit and use their own tool. But I do agree that redsn0w tends to be more stable than the tools rushed by chronic dev. We will have to wait and see!

    Either way, I'll jailbreak at any costs! Or switch to Android.

    Agreed, when I found this site earlier in the week, there was no way I was going to read thru 1200 old posts to find out nothing has happened yet.
    I have already subscribed to this thread. :)

    pod2g just posted:

    iPhone 4S and iPad 2 untether to be released real soon
    Hello dear readers,

    I know the wait was long, too much long, but it's about to end! You'd be able to free your iPhone in some hours.

    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.

    This is a little scary I know, but the chance you break something is really small, since we made lots of tests to verify the process on different devices. But it is the first time we use the backup / restore functions of iTunes to install software, and there are maybe things we are not aware of.

    As you already know, different security researchers put a log of energy to work out the different issues we had to install the untether on new devices.

    Thus, a unified PayPal account was opened so that everyone who worked on the A5 exploits will receive a fair split of your contributions. Here is the link : contribute
    As usual, contributions are not needed but are appreciated by developpers. By the way, thank you very much again for everyone who already participated. This is real nice.

    Here is the complete list of Absinthe supported devices :

    iPhone 4S running iOS 5.0, 5.0.1 (9A405 and 9A406)
    iPad 2 Wifi/GSM/CDMA running iOS 5.0.1

    Also, here is MuscleNerd's which explains the whole story in a really precise way: iPhone Dev Team blog post

    Exciting! But again, wtf? Some say a few hours, some say a few days.

    How do you gather that from that post? pod2g doesn't make the tools at all, he finds the exploits. After he hands off the exploits, he's done. I think the command line tool is for those who prefer to use it over running a GUI, sort of how you use command line on Android tools.

    Half of the "drama" of the jailbreak teams come from stuff like this

    Yea I think there have been CLI jailbreak options in the past too. I don't think they would release it half-baked to the community.

    I can't even download or install itunes, let alone run a program in admin mode at work.

    So at this point, take all the time you guys need :D

    I don't think it's any drama. It's just that they're using a new method, and they realize that no matter how much they test, there are so many different computer configurations out there that there's bound to be some issues that they won't find until after release
