unlock 3.1.3

Some good news for those of you who accidentally updated their iPhone to 3.1.3 and are now stuck without being able to unlock or downgrade.

Sherif Ashim announced today on Twitter that he successfully crashed the 05.12.01 baseband, which really is step 1 in finding an exploit to unlock it. Later on, MuscleNerd confirmed that it was a totally legit find.

What does this mean? Well, this means that at the time you’re reading this, the Dev Team is probably working on turning this exploit into an iPhone 3.1.3 unlock.

iPhone OS 4.0 is still months away so I wouldn’t be surprised if the Dev Team released this 3.1.3 unlock instead of saving it for 4.0.

Early updaters rejoice! An iPhone unlock for baseband 05.12.01 is on its way!

    Does that work on the 06.04 bootloader?

  • Isaac

    I accidentally updated my Iphone OS to 3.1.3. All i get is a screen showing a USB cable + ITunes. There is no way for me to turn off 3G or access cydia. How can i unlock my Iphone 3GS with 05.12.01 firmware? Please healp!

  • Ihor

    unlock depends on your baseband….. If it is 5.8 or lower you’re lucky…. other way you have to wait as we all do

    but jailbreak you should be able to do with blackra1n… not sure if it works with 3.1.3…. if not you still can go back to 3.1.2 and do it

    I just unlocked my iphone 3.1.3 with baseband 5.12.01. I looked at Dev Team’s open source code and I rewrote the code with my own algorithm. It took me about two weeks. Thanks Dev Team for the source code!!!

  • Ihor

    dude, what bootloader are u on?

  • NoUseFor

    Can we download it somewhere to try? As Ihor siad…what bootloader are you on?

    Sorry, but i sounds like the latest fake.. but i would be glad to try it and be wrong!

  • Nick

    What I don’t understand is I had someone at work here with 4.xxx base band and boot loader and then we upgraded his firmware to 3.1.3 and his boot loader went to 6.2. Someone said on a blog that the boot loader is hardware but how is that the case if it seems like the firmware upgraded it. Apple pisses me off, why lock your f***** hardware and limit its utilization scale. I bought a used Iphone 3G that I cant even use. Dev team says there going to have a unlock for the new firmware and so does geohot but when I asked ih8snow on twitter he was like no one knows! Enough with the jerking around, im considering selling my Iphone and getting android!

  • Help

    Hey , I am having the same problem. I tried using redsn0w to jailbreak and now i’m stuck in itunes mode … please help

  • ss


    I have Iphone 3G running jailbroken 3.1.3, however i used redsn0w 0.9.5 to jailbreak ios4.0 and download it on my iphone …but nothing happened? the even after jailbreaking my software remained unchanged!! its still 3.1.3
    Do i have to first upgrade to ios 4.0 using itunes? and then jailbreak 4.0 using redsnow?? but that should upgrade the baseband shouldnt it?
    I thought the whole point of jailbreak or an important aspect of it was to avoid upgrading ur baseband when updating the firmware!!
    What am i doing wrong? anyone? any comments?


  • Finally able to Unlock

    Hey, I was able to unlock and jailbreak my phone. I first used redsnow to jailbreak; however, it got stuck in itunes mode. So, then I had to put my phone in recovery mode and restore my iphone. Then I used Spirit to jailbreak (i used my mac, so when I pressed jailbreak and it immedietely said quit — DO NOT PRESS QUIT — it will get stuck, just let your iphone to restart and then close spirit.) Then I had cydia in my iphone and I installed Ultrasnow and it unlocked my phone.

    Hope this helps.
    I am glad i was able to finally unlock my phone.

  • vitaliy

    With the new release of iPhone 4, everyone’s assumptions of having the solution to unlock the iphone 3G & 3Gs with baseband 05.12.01 would be released at the same time. The timing was mainly due to the same release being able to unlock both the 3G / 3Gs and iPhone 4. Without any further delay, get ready to unlock your iPhone 3Gs 3G on 3.1.3 firmware with 05.12.01 baseband using ultrasnow 0.93.

  • dirtyfinger

    spirit to jailbreak
    ultrasn0w via cydia to unlock
    T-mobile is a GO!
    so grateful, THANK YOU dev team!
    i now have an unlocked iphone 3g running 3.1.3 baseband 05.12.01
    So NOT a paperweight.
