Jailbreak your iPhone

Unlock Baseband 04.26.08, 05.11.07, 05.12.01 and 5.13.04 With Ultrasn0w


Musclenerd and iPhone Dev team just released ultrasn0w 0.9.3 in the wild.

A big thanks to Sheriff Hashim for once again discovering an all new crash to made this release possible. Newer version of ultrasn0w is available on Cydia repo, “repo666.ultrasn0w.com” where ultrasn0w is spelled with a zero, not the letter “o”. Following are the step by step instructions to add Ultrasn0w repo and install the ultrasn0w unlock.

Step Seven : Once the source has been added press the large Return to Cydia button.

Step Eight : Press the Done button at the top right of the screen.

Step Nine : Press to select http://repo666.ultrasn0w.com/ from the list of user entered sources.

Step Ten : Press to select ultrasn0w from the list of packages.

Step Eleven : Press the Install button at the top right of the screen.

Step Twelve : Press the Confirm button at the top right of the screen.

Step Thirteen : After installation completes successfully press the reboot.

Step Fourteen : Now press the Home button then power off and power on the iPhone. You do this by holding down the power button for 3 seconds then moving the power slider that appears to the right. Press the power button again to turn on the phone.

Step Fifteen : You should now be able to insert the SIM of your choice!

    Iphone 3G band 5.13… worked fine! thx!

  3. chewda November 29, 2010 Reply

    Yeah Fantastic. Can anyone tell us how to update to 4.2.1. WITHOUT updating the baseband. Instructions for jailbreaking require you to install a 4.2.1 IPSW with iTunes beforehand. Correct me if I’m wrong, but will this not update the baseband to whatever is now current and so all of us who have been really careful to keep our old one have wasted our time since there’s no way back from this and we’ll then have to use a custom iPad based 06.15 version. Any news on a version of Pwnage tool that will keep the old baseband?

    Thanks muchly

    Hey Vinay,

    is there any way unlocking the iphone without the wi-fi or internet connection??

  12. Ahmed June 24, 2010 Reply

    PLEASE HELP or Email me if you can…

    I tried to FINALLY unlock my iphone 3gs with the newbaseband and it was already jailbroken with Spirit. I had Cydia and typed in the “repo” URL in cydia and then it crashed. I can’t even use cydia anymore because everytime I open cydia it just springs back as if the app never opened.

    I didn’t ssh it and I doubt that will work. I tried ireboot AND I even tried to re-jailbreak like 5 times with spirit.

    NO LUCK………The person that can help me overcome this obstacle will be in my prayers!!!

    this is what many others have been waiting for. Want to thank the 1 and only dev team for their efforts! Can’t believe ppl would pay to get their phone unlocked when its all free. Pass on the word. Thanks again to the Dev team. Peace out 😉

    I have the same problem as Testing3000. Could the Dev Team let us know how to unlock the iphone if you do not have it activated or have Cydia installed? Is there an offline method one can use?

    I have an iphone 3gs 3.1.3 baseband 5.12.01 stuck at the itunes connect screen.
    Most of the JB and unlocks that i have seen are with phones that are working.
    Can you please guide me as to how i can go about first Jailbreaking my phone and then unlocking it..
    Would be highly appreciated if someone can help me with this.


  23. Testing3000 June 23, 2010 Reply

    Please help~!
    I know now there’s a software in cydia that allow us to unlock the phone…

    but…what with people whose phone was not even activate yet?
    we’re all stuck in the “emergency screen”…
    could the dev team do something on it…

    I was waiting…thought such software(to activate) would come out…
    but now…this software only supports jb and unlock…
    how’s now?

    thanks in advance 🙁

    from a depressing iphone owner…which is hating apple and himself(for updating to stock 3.1.3)

    First to submit a post on a forum and it might be helpful to others:
    I have 32GB iPhone 3GS 3.1.3 with baseband 05.12.01 (new bootrom). I able to use my iPhone since I borrowed AT&T sim card then I made it into air plane mode so that I can just use the itunes functionality 🙂

    Then since I saw this forum, I downloaded “spirit” that jailbreaks my iPhone and install Cydia. Then spirit successfully jailbroken my iPhone then I followed the above instructions and its successful. I’m using now a local sim and phone calls are clear. As of now, I’m happy and did not noticed any bugs so far..

    Worked on my 3G[S] running 3.1.2 and 5.12.01. Hooray, and many thanks. Now, a few technical questions before I do something stupid:

    1) I’m tethered because I used the geohot unlock back in November when my phone was 3.0 and my baseband was (I think) 5.11.07. I understand there are now jailbreaks/unlocks that are untethered. Should I upgrade to them?

    2) I understand that this unlock, the one I just used today, will unlock me up to OS 4.0 — when is it safe to upgrade?

    I don’t know what more to do.. Anyone that can help?
