How to unlock iPhone4 04.11.08 and 04.12.01 baseband with Gevey Ultra 5.1

April 28th 2012 It has been revealed that the Ultra for iPhone4 on 4.11 and 4.12 was actually using the Loktar_Sun SAM unlock. has recalled these SIMs and will be providing a full refund for anyone who purchased one. Read more on the ApplenBerry SAM unlock scandal.


Now that the SAM unlock method is dead in the water, there are still plenty of iPhone4 users out there who are stranded on the and 04.12.01 , either because they couldn't get the SAM unlock working or because they didn't do it on time. Luckily, during all the hoopla over the SAM unlock, Gevey released a new SIM hack that works on the 04.11.08 and 04.12.01 basebands and is even compatible with iOS .

Now obviously this is not the ideal unlocking solution as it is a hardware unlock which means it costs money($49.99 to be exact), however, now that the SAM method has been patched by Apple, it is the only solution for unlocking these basebands.

The new Gevey Ultra 5.1 SIM can be found at AppleNBerry, it is currently sold out right now, but I bet that with the demise of the SAM unlock, manufacturers will be putting production into overdrive to accomodate all the unlockers, so keep checking their site to see when they get a new shipment in.

    This gevey works also on 5.0.1 right?

    • JaeM1llz

      Yep, it works on every firmware from 4.1 to 5.1 and with basebands: 1.59, 2.10, 3.10.1, 4.10.1, 4.11.08, 4.12.0

      • Benjamind7

        I heard that this was based on Loktar_Sun’s method and does not work anymore:  

        • JaeM1llz

          Ya that’s why we put that at the top of the tutorial.

          • Dook1o

            is there any update on not being able to unlock with 04.12.01 baseband with the gevey sim?

          • JaeM1llz

            There is no way to unlock that baseband currently with software or hardware.

      • Rajwani Rahim

        i have 4.11.08 ..cant unlock iphone 4 running on 5.0.1 pls??

        • JaeM1llz

          There is currently no way to unlock that baseband.

        “Yep, it works on every firmware from 4.1 to 5.1 and with basebands: 1.59, 2.10, 3.10.1, 4.10.1, 4.11.08, 4.12.0″

        So it unlocks baseband 4.11.08?

        (Why did you write “There is currently no way to unlock that baseband.” in answer to “i have 4.11.08 ..cant unlock iphone 4 running on 5.0.1 pls??”)

        • JaeM1llz

          No, there is no way to unlock that baseband anymore. I posted that comment when the SAM unlock method was still working.

    Can we still use this chip even after the Sam block by apple?
    Thanks guys

    • thescragster

      No, the loophole that the device was using has been patched by Apple, this Gevey sim will no longer work.

  • J G1025

    So, if you have 5.0.1& 4.11.08 you can’t unlock?

    • JaeM1llz


      • Mms10101

        • JaeM1llz

          Nobody knows if or when they will ever release an unlock for that baseband.

    • JaeM1llz

      None of the Gevey SIMs can unlock the 4.12.01 baseband, there is no unlock solution for the baseband currently.

      • Mandyymariee

  • Blue

    • JaeM1llz

      You would have to buy it from eBay or another retailer that ships overseas. Please note that Gevey will not unlock 04.11.08 or 04.12.01 anymore.

      • Blue

         OMG, I think it Can Unlock My baseband, plz Tell me How can i Unlock baseband 04.11.08 ??

        • JaeM1llz

          Like I said, that baseband is not currently unlockable.

        • Hardsession

           Use the SAM method, I did it on my Iphone 4 with firmware 5.0.1 and with the same baseband (04.11.08) and it works. My Iphone is locked to Sunrise swiss gsm operator and it’s working with a Portuguese gsm operator.

          • JaeM1llz

            The SAM method has been closed for quite some time now.

          • Surrender

            BB 4.11.08 can be downgrade with the normal GEVEY SIM. I’ve tried it, it works!

          • JaeM1llz

            There is absolutely no way to downgrade or unlock the 04.11.08 baseband.

          • Nuno Tomás

  • enternet worm

    false statement you r giving they dont have any Gevey for BB 4.11 or 4.12. u r misleading people here…

    • JaeM1llz

      No I’m not, if you would have read the top of the post you would have seen that at one point there was a Gevey for those basebands but it was based on the Loktar_Sun SAM method so once that method was patched, as were the Geveys for those basebands.
