Dev Team Provides More Details About Untethered Corona A5 Jailbreak For iPhone 4S and iPad 2

Jailbreak iOS 5.0.1 Redsn0w

iPhone Dev team has just published a post titled “Corona A5 jailbreak nearly ready to pop! “, which provides more details about the untethered jailbreak for iPhone 4S and iPad 2.

They’ve confirmed that the jailbreak programs will be released soon and they’re currently in the process of fixing some of the remaining bugs.

Dev team writes:

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.
iPhone Dev team has also provided the following details about the firmwares supported for each of the A5 powered iOS devices:
  • iPhone4S: 5.0 (9A334), 5.0.1 (9A405) and the “other” 5.0.1 (9A406)
  • iPad2: 5.0.1 (9A405)
Dev team has also given the following advice to users who are interested in software unlocking their iPhone 4S:

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.

If you love what these guys are doing, don’t forget to give donations to the jailbreak dream team (details on how to contribute are available on Dev team’s blog).

Let’s hope they will make Sunday a funday for all us eagerly waiting for the untethered jailbreak for our iPhone 4S and iPad 2. We’ll let you know as soon as the jailbreak programs are released so stay tuned here at iPhone Hacks or join our Facebook Fan page or follow us on Twitter or add us on Google+ or subscribe to our RSS feed.
