Ultrasn0w updated for iOS 6.1

By , Feb 7, 2013

ultrasn0w 1.2.8

Between the rise of third party vendors and the recent change in DMCA policy, the need for iPhone software unlocks is steadily dwindling. But that doesn’t mean that the method is obsolete, as there are still many people out there with older iPhones.

And if you happen to be one of those people, you’ll be happy to know that MuscleNerd has confirmed that Ultrasn0w was quietly updated this week to support iOS 6.1. So if you’re on an eligible device and baseband, you can unlock on the new firmware…

As MuscleNerd says, Ultrasn0w 1.2.8 works with 6.1 and is already out in Cydia. You just need make sure that you have either: an iPhone 4 on baseband 01.59.00, or an iPhone 3G/3GS on basebands 04.26.08, 05.11.07, 0.5.12.01, 05.13.04 or 06.15.00.

Remember you can check your iPhone’s baseband by opening Settings > General > About > Modem Firmware.

If you’re on one of these firmwares, you’ll have to make sure that you don’t update your baseband when you update to iOS 6.1. To do this, you can use RedSn0w, just open the app and click Extras > Even More > Restore and choose not to upgrade BB.

If you need help with this, click here for our step-by-step video tutorial on the process. It’s older, but should still work.

Now if you really want to make your life easier, we can only suggest using an official factory unlock such as ChronicUnlocks.

Any questions?

    HI! I need help, I made a mistake on my first attempt to thether jailbreak my 3Gs Iphone, (is not a new iphone from 2011 after week 28) and now I have no Cydia any more as the first time I attempted Jail break I lost it on the Itunes update of firmware which was recommended, tried to use Redsn0w to reinstall Cydia and it doesn’t install it. I have a base band 05.13.04, old bootroom. Can I download ultrasnow to my macbook and do the jail break from there? I wish I knew about you guys before I attempted the stupid way I attempted the jail break it, now I am really in a bind and don’t know what to do. Can someone help me? Any suggestions?

    Hey.

    What if my modem firmware is 05.15.04?

    Thing is, I’ve tried to install Ultrasn0w, but it ruins my signal to my operator… When I remove it, everything works just fine again.

    (I’ve got an iPhone 3G.)

  • Patrick Gallagher

    Please forgive if this is a noob question as I’m still quite new to all of this but is anyone working on unlocking the 04.12.05 baseband? If you’ve upgraded is it just a case of waiting until someone cracks it or are you stuck with an unlockable device?

  • J’adore Lee

    I have an iphone 3gs with ios 6.1.6 and a baseband of 05.16.08. The serial number on the sim holder is different than the serial number in my setting, but I can no longer get to my settings because my phone had to be factory reset. I really just want to get this phone working because I desperately need it for work and personal matters. Any help would be much appreciated!
