Ultrasn0w 1.2.8 For iOS 6.1 Released


If you depend on Ultrasn0w, the software based solution to unlock your iPhone then we have some news.

Yesterday, MuscleNerd of the evad3rs dev team revealed that he had released a new version of Ultrasn0w for iOS 6.1 along with the launch of the evasi0n jailbreak on Monday.

MuscleNerd tweeted that Ultrasn0w 1.2.8 is compatible with iOS 6.1.

Just like the previous versions, Ultrasn0w 1.2.8 will only support the older basebands such as 04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00 for iPhone 3GS and baseband 01.59.00 for iPhone 4.

If you want to unlock your iPhone using Ultrasn0w then it is important to preserve the baseband using tools like Sn0wbreeze and Redsn0w to upgrade to iOS 6.1.

Due to availability of cheap IMEI based permanent unlocking solutions and legality of unlocking in countries like the U.S, we doubt Ultrasn0w will ever be updated for basebands for the newer devices.

Thanks everyone for the tip!

    Pardon my ignorance but wasn’t iPad based band i.e. 06.15.00 update proof? Or did i misread it because i certainly read something in that line somewhere :-(

      Yeah there’s no way to update the BB or downgrade… If on 6.15 ipad BB…. Bad thing is you won’t be able to factory unlock too…. And I’m pretty sure a lot of iPhones out there has the 6.15 BB and won’t be able to use the GPS

      ipad are all unlocked. so whats the point of ultra snow, only verizon non 4g ipad is not unlocked but dose not have sim slot so it dose not matter.

  • Jimjamurface

    That is my understanding because it was such a high number. Also, as far as I know it’s only usable on the 3GS and it sucks at best. Although the 3GS can be downgraded so it doesn’t matter.

    • KOOMOO

      I’m pretty sure the IOS can be downgrade but not the BB it will stick with any IOS for 3GS and 3G iPhones and nothing has been released to revert back to stock BB or present BB

      • JCT

        there was a trick for 2 out of 4 i phone 3g to downgrade baseband had something to do with the chipset the first 2 versions were downgradeable none of the others though


    Great news that they updated ultra snow…. But your better off paying a buck on eBay to get it factory unlock and then jailbreaking it.. Just my 2 cents

    hi guys, thanks for the upgrade, but even after loading ultrasnow have low reception on iphone 4. used sn0wbreeze to jailbreak 6.1 ios

  • DayMare

    Just tried updating to 6.1 after backing everthing up (Blobs the lot) on my iPhone 3GS 6.15 baseband.

    Used the new Sn0wBreeze to create a custom IPSW and once it was up and running, installed the new UltraSn0w 1.2.8

    Now it’s just stuck saying ‘Searching’ and ‘No Service’

    Any help?
