Dev Team Working on “Very Promising” iPhone 4S Unlock

By , Nov 27, 2011

Dev Team frontman and unlock guru MuscleNerd has given an update on a new unlock for the newly-released iPhone 4S. According to MuscleNerd, a “very promising” unlock for the new handset is “in the works.”

While iPhone 3GS and iPhone 4 owners with older basebands have been able to unlock after jailbreaking for awhile now, there’s a whole set of newer basebands waiting for an UltraSn0w update.

UltraSn0w lets jailbreakers unlock the iPhone for free to use on different carriers, and there hasn’t been a baseband update for quite some time. Currently, UltraSn0w for iOS 5 supports the following basebands on the iPhone 3GS: 4.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00. The 01.59.00 baseband is also supported on the iPhone 4. There are multiple iPhone 4 basebands that have yet to be unlocked with an UltraSn0w update.

The Gevey SIM hardware unlock supports the same basebands as UltraSn0w on iOS 5. You must preserve your baseband when jailbreaking (tethered or semitethered) by using either RedSn0w or Sn0wBreeze if you want to keep unlocking.

Obviously, an unlock for the iPhone 4S will require a jailbreak, and an untethered jailbreak is also in the works for iOS 5. The Chronic Dev Team gave an update late last night on the status of the iOS 5 jailbreak. Hackers are working feverishly to uncover stable exploits, and they want your help.

MuscleNerd hasn’t given an exact ETA on the UltraSn0w update, but potential unlockers with newer basebands shouldn’t be left out in the cold much longer.

    I need to ask… Why doesn’t the teams just work together? I feel like they don’t and they try to beat each other at who can JB first. Or is it just me?

      Competition is a good thing. It keeps dev teams on their heals. If all the developers worked together on the same team there would be no motivation to release as quickly as possible.

        That’s true, however it makes me say “you can unite as a team and make these tools faster, more stable, and can burn less exploits.”

        I do see your point, but I think the team game would give Apple more of a run for their money.

      For the same reason that Pepsi and coke, apple and google, ford and honda or Nikon and canon don’t work together.

    Unlock is nice and all, but I really do hope this means that they are anticipating a jailbreak release in the near future. ~crosses fingers~

      A jailbreak is required to unlock. Also, if you look at the picture, it’s showing a 4S with root ownership. :)

    The tweet says 4s only not iPhone 4. Boo!

    • http://twitter.com/YarikGo Yaron Goikhman

      the base band is the same 4s unlock=4 unlock=3gs unlock as long as the modem baseband is the same the unlock is universal

      • http://twitter.com/mrmberman Marc

        All iPhone versions have different modem baseband firmwares, some unlockable, some not.

        You couldn’t be more wrong… basebands are different on all devices. This unlock that is being worked on is for iPhone4S only.

    • http://twitter.com/iphoneblogr iphoneblogr

      This news is about unlock only which has nothing to do with jailbreaking. When the jailbreak is released it will be released for all devices at the same time.

    FOR THE LOVE OF ALL THAT IS HOLY WHAT DO I HAVE TO DO TO GET A BB 4.11.08 UNLOCK?!

    Call me ungrateful and what not but all I’m asking is for a BB compatibility.

    • http://twitter.com/alexjdz Alex Diaz

      Exploiting basebands is not the same thing as updating for firmware compatibility.

      • Anonymous

        True, didn’t explain myself correctly.

        ALL I WANT IS BB 4.11.08 TO BE ADDED TO ULTRASN0W, jeez, not even asking for an untethered jailbreak (which I don’t seem to find necessary atm)

      • http://twitter.com/alexjdz Alex Diaz

        Exploiting basebands is more difficult thatt exploiting to get a jailbreak, as they’re more closed.

    What part of muscle nerds new news stating only iphone 4s dont you understand? Why does your headline say iphone 4 and 4s?

  • Ryan Rizo

    is there any news on a unlock for the iphone 4 baseband 4.10.01?

  • http://pulse.yahoo.com/_A5OKDDGFAUWTHMBNRI7WQAOA5Q snap

    is 4s 5.0.1 unlock-able yet?

    • http://twitter.com/billk77 Todo Goldworthy

      the baseband is what gets unlocked not the ios version. if you have a jailbreak, get the ishshit app and save that way or get tinyumbrella to save them. 5.0.1 became untethered just recently for all A4 devices, 3gs new boot applies here too. the i4s is an A5, so the untether does not apply. if you have an i4, not 4s, with 1.59 baseband, preserve that thru a custom before you update or you’ll lose that band. These hackers are working excellently, if you need it quicker, start assisting them or be patient.

    Any update on when there would be a 4S running 5.0 unlock? I read back in November that an Ultras0w unlock for the newer basebands was almost ready. They were just waiting for d 4S jailbreak. Someone please fill me in. Thanks.

    i believe ultrasnow , snowbreeze as wel as redsnow team have a unlock solution for 4s , bt i think they have a negotiation with apple… also they(ultrasnow,snowbrz,yellosnow,geo hot) hav got a huge amount frm apple & that’s the reason fr delaying unlock.
