Ultrasn0w For iOS 4.2.1 To Unlock iPhone 3GS, iPhone 3G To Be Released On Sunday

Unlock iPhone 4

We have some good news for folks who want to unlock their iPhone.

MuscleNerd of the iPhone Dev Team has just confirmed that the eagerly awaited unlock for iPhone 3GS and iPhone 3G for iOS 4.2.1 will be released on Sunday.

MuscleNerd announced the good news via the following tweet:

Good progress today…everything is on track for updated ultrasn0w by Sunday/Funday at the latest (longer for iPhone4!)

iPhone Dev team had mentioned earlier that the unlocking solution for iPhone 4 users will need more effort and were not in a position to provide any further information.

The updated version of Ultrasn0w will unlock baseband 05.14.02 that was shipped with iOS 4.1 or lower.

However, it is not clear if the updated Ultrasn0w will unlock baseband 05.15.04 that was shipped with iOS 4.2.1. So users who want to unlock their iPhone should avoid upgrading to iOS 4.2.1 for now. iPhone Dev Team had warned users immediately after iOS 4.2.1 was released:

As always, ultrasn0w unlockers please stay far far away from this official firmware (and all official firmware). Wait for the ability to create custom 4.2.1. IPSWs that don’t update your baseband!

iPhone Dev Team has already released a new version of Redsn0w to jailbreak iOS 4.2.1 for iPhone 4, iPhone 3GS, iPhone 3G, iPod Touch 4G,iPod Touch 3G, iPad and Apple TV 2G.

As always, we’ll let you know as soon as the updated Ultrasn0w is released so stay tuned here at iPhone Hacks or follow us on Twitter or subscribe to our RSS feed.

      yes sir! I just did it!

  • http://profile.typepad.com/iphonehacks iPhoneHacks

    No, you shouldn't update to iOS 4.2.1. You should wait for Dev team to release PwnageTool to preserve the baseband so you can then use Ultrasn0w to unlock it.

    Thanks for clearing the DOUBT of the new baseband iOS 4.2.1 has.. it seems Taimour of Redmondpie just posted it wrong and everyone started following it and wrote all over the internet.. MuscleNerd never mentioned anywhere that it is coming for the new baseband or iOS 4.2.1!

    anyways Thanks!!

  • Ayyan

    It should work on iOS 4.1 as well. However, we will confirm when it is released.

  • alan

  • Unjailbhroken 3GS Locked/iPhone4 jailbroken Fac-Unlock

    1. Guys, technically… does an unlock (ultrasnow)purpose have any kind of bearing if u do not wish to change/shift your carrier but jst want ur iPhone Jailbroken? & after w/c, a later version goes out & u just wish to upgrade & rejailbreak again? Any complications w/ that?
    2.Assuming you have a fac-unlock iPhone, jailbroken state, & wish to upgrade to the most current iOS version… does it involve any kind of hazard if u simply upgrade & use appropriate JB tool not considering whether ur BB increments as well?
    Thanks very much! Just need technical infos to get enlightened w/ the JB/Unlock world. :)

    Iphone 4 unlock is the question.

  • Meidas

    Hey, guys. Quick question. Is it possible to upgrade my iPhone 4 to iOS 4.1 using this PwnageTool now? I know that during iOS upgrade iTunes contacts apple server to check if it is the newest version.. and now we already have iOS 4.2.1 released. I need unlock, so I cannot upgrade to 4.2.1. Thank you in advance for the answer ;)

    1. Guys, technically… does an unlock (i.e.,ultrasnow)matter or has any kind of bearing if u do not wish to change/shift your carrier but jst want ur iPhone Jailbroken? & frm a JB state, a later iOS version releases & u just wish to upgrade to that current iOS & rejailbreak again? Any complications w/ that?
    2.Assuming you have a fac-unlock iPhone, jailbroken state, & wish to upgrade to the most current iOS version… does it involve any kind of hazard if u simply upgrade & use appropriate JB tool not considering whether ur BB upgrades as well? Any hazards w/ such case for a factory unlock iPhone?

    What alternative phone do you rely on, while iphone remains unlocked? I am using an old Nokia 1100, which boasts of having sold 200 million pieces! Poor man’s phone, cheap and works.Though I do want my iphone back, I am so deeply stuck in recovery mode with the Itunes + USB logo screen! Till then, the Nokia phone just rings along….

    Can baseband 05.14.02 be unlocked?

  • cooldudeleo

    Hi,
    I have an iPhone 3GS 16GB

    I am also stuck on ios 4.1 with baseband 05.14.02, bootloader 6.4.

    I was able to jailbreak the iphone using the limera1n, but the BB 05.14.02 didn’t unlock with ultrasnow 1.2

    I am not willing to unlock the phone with baseband 6.15 as there might be issues with GPS

    Will there be an unlock released for BB 05.14.02 ever? Can someone help me unlock my phone making sure that I do not loose any major functionality like GPS.

    thanks
