iPhone 3GS 3.1.3 Unlock Now Available

The iPhone 3GS and 3G 3.1.3 unlock has been released today. The unlock comes from the iPhone DevTeam who have managed to unlock basebands 04.26.08, 05.11.07, 05.12.01 and 05.13.04. iOS 4 also is unlockable although that particular unlock is not available just yet. We expect that to arrive shortly.

From iPhone DevTeam on Twitter…

“ultrasn0w 0.93 released! Cydia repo is repo666.ultrasn0w.com. Works with basebands 04.26.08 thru 05.13.04”

All the details are in the tweet, so give it a try and let us know how it goes. We have tested this evening on 3.1.3 and it works successfully.

    • neha malhotra says

      deepesh how did you do it? i have a MC model with same configuration. can u tell me the whole procedure from a to z. thanks 🙂

      • Deepesh Jain says

        First of all u need to install the ultrasnow V 0.92 if V 0.93 is not available while searching in Cydia.
        Once u install it you will see the updates of 0.93 in cydia.once you install the ultrasnow Version 0.93 the iphone will get restarted.You power off the iphone again and put ur SIM and then Power ON the iphone…
        Now u will be good to GO !!

        • Deepesh,

          the problem is, i don’t have cydia on my phone since its been updated accidentally to 3.1.3 with BB 05.12.01 around a month ago. How do i first get cydia on the phone, then try to unlock it?

          Can you help?

          Cheers, Pankaj

  9. I have a 3GS running 3.1.3 firmware with the 05.12.01 bb..however, my phone is stuck on the connect to itunes/emergency call screen, because I do not have the original sim card to activate it.

    Same case with Kori…
    My brother bought the phone in US last time…
    I actually updated to stock 3.1.3 firmware…shit*…
    now…I’m also stuck at emergency call screen…

    I thought the Dev team would released a solution for that in June…
    and now they released software…for JB and unlock only…
    how about activate?
    Will there ever be a software to activate this 3.1.3 with new bootroom?
    pls…dev team…do something… 🙁

  13. Do you need to have a active sim on the phone to perform the unlock ?

  14. no need for active SIM, unlocked my 3.13 ! although cydia does hang in the middle, but it still unlocks eventually! Kudos to them!

  15. I jailbreaked with spirit, installed ultrasnow 9.3 with cydia on my iphone3gs and although it know shows vodaphone uk in corner and multiple carriers in options…….when I ring, it says this persons phone is undeliverable?

  31. thks soooooooooooooooooo much iphone dev team,,,,u re the best….baseband 5.12.1 on 3.1.3 now unlocked..oh gosh thnks alot guys.

  32. I am kind of a newbie, but have been trying ti find a way to safely jailbreak and unlock my phone.
    I have a 3gs 3.1.3 (ATT original issue) with the new bootrom and a Mac OSX 10.6 for jailbreaking. I have been reading about Spirit for jailbreaking, but they say you can’t use Itunes 9.2. I haven’t upgraded to IOS 4 because I thought it may make it more difficult to jailbreak..but I do have the problem of itunes 9.2
    Also, I have the original ATT SIM, but I want to unlock to go to T-Mobile. I have a SIM for T-Mobile, but it is barely 60 days old and they say that they are inactive after 60 days…which means I may have to buy a new SIM. I don’t think testing with hy husbands sprint SIM would work because they are not GSM? I really just want to make sure I have the right method down before I do this because this is my only/primary phone and I need it up and working unlocked (as opposed to my currently locked phone with ATT). I don’t want to jailbreak if there is no hope for unlocking in the future. Please, this is the only way I can keep my iphone b/c it is waay too expensive with

    • p.s. I hate snow doesn’t list any support for MC (New bootrom) phones. I am learyof running forecast on i h8snow if it is not compatible with my device. Again..I am just going off of research I have been doing for awhile and just want a no B.S. solution. Also did Geohot give up on the 3.1.3 new bootrom?
      Did the Dev team give up on a pwnage for the 3.1.3 new bootrom because they are working on IOS4 and iphone 4? If I install Spirit, will I never be able to use a pwnage program by Dev Team…even if they come out with better versions for my phone? Thanks again

    my email is [email protected] what i can do for to jaillebreak it? Thinks

  35. All you people asking for personal help are stupid. Do you think they’ll reply to you personally and help you with every little bump on the road? I mean you guys are lucky enough to receive this program for free.

  36. I have a 3GS which was upgraded to version 4.0, any news as to when the program to unlock this version will be out??

  37. I’ve never used twitter, can someone post the exact link on where the guide is?

    • The quote in the post is the quide. That quote is the whole tweet that was sent. Might be worth you checking out the iphone dev team site for full instructions.
