Sn0wbreeze 2.3 Beta 4 For iOS 4.3 Released; Allows Users To Unlock iPhone 4 Baseband 01.59.00, iPhone 3GS Basebands 05.13.04 Or Earlier Using Ultrasn0w

Sn0wbreeze v2.0

iH8sn0w has released a new version of Sn0wbreeze – v2.3 Beta 4, which will allow users to use Ultrasn0w to unlock iPhone 4 baseband 01.59.00 and iPhone 3GS basebands 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04.

iH8sn0w had released Sn0wbreeze to jailbreak iOS 4.3, the unofficial PwnageTool for Windows last weekend.

Sn0wbreeze 2.3 beta 4 includes the following changes:

  • ultrasn0w now works for basebands (01.59.00 / 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 / 06.15.00)
  • ultrasn0w is NOT compatible with the folllowing basebands! (02.10.04 / 03.10.01 / 04.10.01 / 05.14.02 / 05.15.04)
  • Upgrading your iPhone 3GS baseband to the 06.15.00 iPad baseband hack to unlock MAY cause you to lose your GPS!
  • Fixed minor GUI + iBooty bugs.

Sn0wbreeze is useful for users who have their iPhone on older baseband (iPhone 4 baseband 01.59.00 and iPhone 3GS basebands 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04) and want to unlock their iPhone as it allows users to create custom iOS 4.3 firmware file that is pre-jailbroken, which can be used to preserve the baseband from getting upgraded using the “Baseband Preservation Mode” so that it can be unlocked using Ultrasn0w. You can check your iPhone’s baseband via Settings –> General –> Modem Firmware.

Sn0wbreeze 2.3 beta 4 supports only a tethered jailbreak currently so users will have to use iBooty to boot into jailbroken state (which is installed on your desktop after running Sn0wbreeze 2.3) if they need to reboot their iOS device.

Sn0wbreeze 2.3 supports the following devices:

Sn0wbreeze is available for Windows users. iPhone Dev Team is yet to release PwnageTool to jailbreak iOS 4.3 for Mac users. There is also no software solution to unlock iPhone 4 basebands – 02.10.04 (bundled with iOS 4.1), 03.10.01 (bundled with iOS 4.2.1), 04.10.01 (bundled with iOS 4.3) or iPhone 3GS basebands – 05.14.02 (bundled with iOS 4.1), baseband 05.15.04 (bundled with iOS 4.2.1) and baseband 05.16.00 (bundled with iOS 4.3).

We’ll let you know as soon as there is any further updates so stay tuned here at iPhone Hacks or join our Facebook Fan page or follow us on Twitter or subscribe to our RSS feed.

Please note that jailbreaking and unlocking your iOS device may void its warranty so proceed with caution and at your own risk. Please don’t forget to backup your iOS device before you proceed. You can refer to this post for instructions on how to backup your iOS device.

You can download Sn0wbreeze 2.3 beta 4 from iH8sn0w’s website.

As always, please let us know how it goes.

    Tethered or untethered ?

    • HusAli

      Okay, i just noticed that it’s tethered. Pass 😀

  • lknight

    You will lose GPS if you use iPad baseband. There is no MAY. It is you WILL LOSE. Stay away from 6.15 basebsand. Don’t confuse yourself with Cell Triangulation (not GPS).

  • There is also no software solution to unlock iPhone 4 basebands – 02.10.04 (bundled with iOS 4.1) EPIC FAIL 🙁

        Then you probably should have gotten an official carrier OR not gotten such a “crappy” phone…


      • Paradox

        So the phone is shitty because your not using it on verizon or at&T .. but onc eyou unlock it to the service provider you want, it won’t be shitty? Sounds like you have serious problems with dimensional reality. In this one, its not the service provider that makes the phone.

  • Hari

    My Iphone 4 was BB 01.59.00 But when i update to IOS 4.2.1 it change to 03.10.01. can get back to BB 01.59.00 and unlock it.

    • CG

      You can downgrade baseband once it updated it’s updated there no going back. So you screwed for unlock until they figure out how to unlock it.

      • CG

        I meant you can’t.

  • Palmi

    Are there any news on the baseband 05.15.04? Either a downgrade or are they working on a unlock?

  • Michael

    Not trying to sound ungrateful but this is yet another redundant and repetitive headline. Sorry, but it’s boring now!! Same old story, unlock baseband iphone 4 01.59.00 only. Oh and yet another tethered jailbreak……
    You just wonder if the hacking community is missing Geohot!!!

    • jan

  • que_pasa_hombr3


  • Delay

  • ZaSaGarip

    Anybody who understand what it is?

  • bill spires

  • Kenny

  • Kenny

    Jailbreak tool is not working. iBooty keeps going in a loop. No solution for it yet.

  • ashmeh

    Has anyone tried to update iOS to 4.3 for an unlocked 3GS with 05.12.02? I need someone to provide results before I give it a shot. Thanks!

  • Ray

    I successfully jailbreak my iphone 4 ios 4.3, baseband 04.10.01 and furthermore I can reboot my iphone untethered using this version of Sn0wbreeze 2.3 Beta 4. Hahaha Feel great….. thanks to people who devoted their time for this tool.

    • Ray

      Sorry I retracted my previous comments about untethered, has to be tethered when reboot otherwise Cydia will not work. 😉

  • Van Dong

    Thank you very much

  • fas

    The need of the hour is unlock for 2.10, 3.10 not anything else.

  • hittsy

    any one know when unlock comes for baseband 2.10, 3.10

    • Limping behind


  • Good work but I still hope untethered jailbreak will be released soon

  • Roi Poulsen

    Keep up the good work guys.. 🙂

    • Limping behind


  • Bad Apple

    here’s an idea: why not charge $10 or $20 for the unlock > there would be enough people who would pay for it, myself included > this was dev team would not only get the satisfaction of success, they would also get paid for it.

  • Thank you need that so bad

  • Apple Shit

    No More Tweet tweet tweet tweet????? FuckShit!

  • Limping behind

    Hi, may I dare to strongly suggest to the Dev Team and competing hackers, that you politely simply give up and bow out to Apple, concerning unlocking their later basebands? Realistically, now there are ONLY two choices to get an unlocked phone….a) you pay for factory unlocked….or b) you keep believing in the tooth fairy too.

  • FredMc

    Give up on the unlocks guys, I would prefer they use their time keeping up with jailbreaks.

  • Andy

    I just got the gervey sim and yay my iPhone is unlocked now but the problem i have no reception alot of the time and you have to do the whole airplane on and off dial 112 everytime which is frustrating.

    So still waiting for a 4.2.1 03.10.01 unlock

  • Why didn’t these gurus work out our friggin GPS was going to be fucked when they told us to jump on the miracle ipad baseband 6.15.00? It was not until punters got screwed they started advertising this anomaly….we trust these blokes and got burnt.And to all you wankers I do not want to hear Oh bad luck your fault…We waited months and months for that shitty fix

  • gerald yamoah

    When actually is the release date for iphone 4 version 4.1 really coming out in Ghana! We really need to use our iphone ok! Pls don’t let us look stupid ok!!!

  • Kenny

    Sad.. very sad..

  • Stiiiiil waiiiiiting


  • supernova

    huh??? did i just got out of a time machine?? this is old news! wtf?!?!?

  • David

    Hi guys – I need help. I have a iphone 4 and it was jailbroken via “jailbreakme” and unlocked by “ultrasn0w.” and firmware 01.59.00 I want to upgrade to 4.2.1 or higher. How do i go about doing it. i know cydia preserves my baseband?? Help please!



  • Peter

    Ok this is my problem I originally had 4.01 installed on iPhone 4 which was jail broken, I messed it up by using erase everything thru iPhone and was stuck on apple spinning logo. I then made it work again by doing a custom restore with 4.2.1 restore with tiny umbrella in background preserving my unlockable baseband which I need. Once I finished restore thru iTunes I was stuck in dfu but made it work again with redsnow for windows by forcing a bootup then I unlocked and got it to work. After a minute my screen went to sleep and was dead and couldn’t come on. I tried redsnow again and nothing it doesn’t work, no custom restores work thru iTunes again either, they all go thru on computer successfully but my iPhone is just a black screen. The baseband is definately still preserved as I used service with simple mobile and checked it on about, it said 4.2.1 and baseband 01.59. After researching this problem I see many people have it- it’s called a “dfu loop” , any ideas what to do? Maybe restoring with originally firmware and tiny umbrella in background? I’m kinda scared it may still update my baseband, please help somebody 🙁 sux to be without an iPhone, ESP paying $520 for it that I can’t even use.

    • annoyed iphone owner

      Try downloading RecBoot to see if it will kick you out of DFU mode.

  • Ehsan
