Update :

Our users informed us that Apple has blocked iOS 5 unlock with beta 2 update. But you can still unlock iOS 5 if the baseband is preserved to 4.10.01 . Currently iOS 5 beta 2 updates your baseband to 4.11.06 and makes the Gevey Sim inactive .

To Unlock iOS 5 you need to preserve the baseband while updating to iOS 5 . For this use Snowbreeze and create custom iOS 5 ipsw and install it via iTunes . Read the Snowbreeze Technique for details .

    Apple blocked the Gevey Sim in IOS 5 since Beta 2…

    • Iphone Blogger says:

      Thanks for the update Ace . But we can preserve the baseband on iOS 5 beta 2 and later using snowbreeze and unlock it with Gevey Sim.

      This seems to be a possible solution . however i have not tried it myself

      • Ace says:

        Hope so! It would be great if we can use it on IOS 5. So Wait & See :)

      • sky says:

        hay guys, where can i buy that Gevey sim? can anyone provide me exact name for that card for ISO 5.0.1 or link would be great.

      • rockitup says:

        Try Amazon if possible, or Applenberry to get the Gevey Sim. Gevey Ultra is the latest version but Gevey Pro works fine

        I used Gevey Pro Sim a few days ago and it worked unlocking 5.0.1 after preserving baseband. The only problem I came across was I kept getting Error Code 1604 which according to Apple is a problem with USB Port not recognising the phone.

        I googled the error code and found a site recommending using iReb to assist with the unlocking process (I was not jailbreaking). After installing that it all worked fine and got full signal after completing the unlock.

        Thanks to all you guys on here for your help with the Gevey procedure, I was a little uncertain after reading the applenberry warning about ios5

    • Lahiru says:

      gevey sim woring on apple official IOS 5..i tried my self and its worked..dont expect the 1 bar after accepting the gevey sim mesage becuse ios 5 will not show it..it will show NO service but u just dial 112 and wait and end it then go to airplane mode and on off it and then wait till u get the message like this “No Sim CARD INSTALLED”then u do the airplane mode on off again..then u done..
      thanks

      • iDon says:

        You’r post is so helpful, hope this will help gevey users which are used to wait that one-bar

      • tenn says:

        Is your phone with 04.11.08 baseband?

      • Ram says:

        Lahiru, Thanks a million. I was just waiting for the one bar to show up for calling 112. But your post helped me to come out of mess. Please all follow the steps given by Lahiru it’s working perfectly fine. I was able to unlock using Gevey sim. I’ve iPhone 4 on iOS 5 baseband 4.10… Thanks once again Lahiru.

      • mandy says:

        please help meeeeeeeeeeee

    • Sal says:

      Hello,

      well like quite a few people i upgraded to IOS 5.0.1, now it is stuck with 4.11.08. tried to have it downgraded but every single error 31xx and 10xx came.
      i went back restoring to 5.0.1 as it didnt even get out from DFU mode.
      now the strange thing is that it connects with the provider for like 10 seconds or so and then again no sim or no service.
      what is the deal about connection for 10-15 secs? SMS that are pending comes.

      • adil says:

        currently there is no way to downgrade your baseband but hope it will e realsed by dv team by the end of this month…then u can thered jailbreak it and install cydia and then insatall ultrasnow and then it will work fine on any network

    • Peter says:

      Hi i got my iphone baseband to 4.11.08.. im using the current ios5.. i accidentally updated d firmware so im guessing i cant use gevey sim anymore in my device.. is there any chance you guys can help me out here??? appreciate it pls thanks!

  2. Eldo says:

    I tried rebel micro sim on IOS 5 (beta) and its working.Hope working on official release of IOS 5

    • Ace says:

      Hey Eldo, on which Beta did you try it?

      • Gp says:

        Well Gevey works on all iOS 5 betas till now (I am on beta 7 & it’s working perfect with 3G & all) but only with preserved baseband.
        When actual iOS 5 will be launched , we will need sumthing like tinyumbrella or sn0wbreeze to update to iOS 5 without touching baseband.

      • Ace says:

        That’s a promising and really interesting news! Thanks a lot Gp :)

  3. Chris says:

    One signal bar does never appear not in 15 secconds not ever. What do I do wrong?

    • Ace says:

      You have to reboot the phone until it appears. Also try to remove the sim and put it again

      • chris says:

        I have made it! despite the fact that the at&t locked iphone runs on 5.0.beta7 with untethered jailbrake with a sim card from a european carrier!

  4. Ace says:

    So Chris does that mean that the gevey is blocked in IOS5 Beta7? You had to use another SIM to make it work?

    • chris says:

      no, it worked with a noble prepaid eu carrier sim. it was amazing as my gevey card is 1 year old, not one of the new models. ofcourse I keep the gevey inside and if I will need to reboot I will have to go through the whole procedure again that is a tethered boot with redsnow and the gevey unlock steps

    • chris says:

      but the gevey unlock procedure I used to make it work was slightly different, I did not call 112 and I changed to manual carrier selection

  5. Pablo says:

    Is it possible to use the gevey with a pre paid sim card? How does it work, can you remove the gevey sim once you’ve unlocked the phone then put your sim in it ?

    • iPhone Blogger says:

      gevey Sim remains inside iphone and yes it works with any sim card

    • Indian spring says:

      Just updated to ios 5 preserving bb using snowbreeze – gevey works fine on a prepaid sim in India…

      • Smasher says:

        if it works in india i am sure it will work in Afghanistan i just updated it in itunes i jailbreaked in redSnow but the problems is sim card

  6. freii says:

    @chris, can you may explain a little more in detail how you made it? I heard APPLE blocked the emergency-call after beta2?

    thanks

  7. chris says:

    I be heard about that too that was why i was so amazed.
    anyway
    step1 I used red snow to jailbrake and install cydia
    step2 redsnow again to boot tethered
    step3 used ifunbox to delete the code key releasetype/key and string/beta/string from the last line of the file systemversion that is located in raw system files/system/library/core services
    step4 reboot again with redsnow tethered boot with the gevey and my sim to activate my iPhone
    step5 answered gevey question turned off 3g and turned on roaming turned on and off airplane mode twice and it worked

  8. Kenneth says:

    I’m using an iPhone 4 with version 4.3.5 and a Modem Firmware of 04.10.01. I’m also using a Gevey SIM Ultra at the moment. Do you think if I upgraded to iOS 5 that it would still be able to find signal with the Gevey Steps? If not, then how would I “preserve” my modem firmware?

    • Indian Spring says:

      Use Snowbreeze to preserve your baseband at 4.10..01 – worked fine for me…

      • Ace says:

        Even the latest RedSn0w allows baseband preservation. Be aware, all these jailbreaks are still tethered

      • Indian spring says:

        Redsn0w for Windows does not have the baseband preservation mode – and the Sn0wbreeze jailbreak seems to be missing something. What worked for me was using sn0wbreeze to create a custom IPSW with just baseband preservation, no jailbreak, restore and then use redsn0w to jailbreak…

  9. Gowtham says:

    Help me in activating iOS 5 after updating using gevey sim… I don’t have original sim card with me and so will it be possible to activate as I cannot even unlock the Phone without activation which happened in previous editions… Thank you.

  10. Hansen says:

    I tried with sn0wbreeze (hactivated) and iBooty – bad result. But when i just made an update with sn0wbreeze (no hactivate) and followed the above instructions (it’s a bit different from the “normal” procedure)- and with the original AT&T sim card .- everyting worked. I’m now running iOS5 with Gevey – perfect :-)

    • deas says:

      hey man, i have the same problem than you, so i try the same steps (no hactivate) but my original gevey sim its doesnt work, it apears the screen i accept an then the signal never show, i try to do it like that but i never accept my sim card. so what exacly did you do?

      • Hansen says:

        I used the original AT&T sim card to activate the phone at the first reboot after installing iOS5. And after that I followed the instructions on this page – and it worked. Hope this is helpful to you ;-)

      • deas says:

        well its unlocked now, i don’t know what i did, but i try like an hour and a Christmas miracle happens. jajaja its working now!!
        but im afraid to synchronizes with itunes because its goning to restart my iphone and it will lose my sim again….

      • Hansen says:

        My phone wasn’t rebooted when I connected it to iTunes. That only happens when the software is updated, and since you run iOS5, you have the newest software and hence iTunes doesn’t reboot your phone.

  11. Juree says:

    I am using gevey sim in iphone4 in pakistan. My version is 4.2.1 and i wanted to ask that will i be able to update it on ios 5??

    • Smasher says:

      Sure you can, but if you know a little much about updating to newer version take a skill than do it or it will lock your iphone for ever.

      Country: Aghanistan

  12. VIJAY says:

    i have updated my gevey sim to ios5 directly through itunes.the modem firmware has been changed to 04.11.08. it shows no service ..kindly helf me what should i do now

  13. Ace says:

    I successfully installed IOS5 on my iPhone4 4.10.01 using the first generation of Gevey Sim.

    Here are the steps :

    1- Use last version of sn0wbreeze to UPDATE with baseband preservation (there are 3 options, it’s the first one). This will allow you to cook a custow IPSW. Then go to DFU mode an restore to this IPSW through iTunes.

    2- Jailbreak with the last RedSn0w. Don’t worry, it won’t update your baseband.

    3- I tried about 5 times removing and re inserting the sim into the phone in order to get rid of the “No sim installed” message but finally it worked.

    Hope this will be helpful,

    Cheers,

    Ace

  14. Aiden says:

    How come my phone only have 1 bar of the singal ???
    Iphone4 Custom IOS5 BB 02.10

    • Ace says:

      Try installing ultrasn0w, it generally fixes this problem

      • Andrew says:

        I have the same situation, and even with 1 bar, sometimes the phone will work, and then sometimes it drops (too often).

        Iphone 4, preserved update with sn0wbreeze 02.10.04, not yet jailbroken but going to try and see if it helps.

        Is there a better bb to try? and if so, how to I update it?

  15. Ace says:

    Andrew, if you update your BB, you will get a BB that is unlockable with Gevey Sim. So better try jailbreak with RedSn0w. It will hacktivate the SIM and bypass the SIM control made by Apple. Don’t forget to install latest ultrasn0w via Cydia. Good Luck.

    • Andrew says:

      Thanks! Not sure if I did it exactly the way you said, but something worked!! I still have 02.10.04 bb, but I jailbreaked with redsnow and installed ultrasn0w and now I have full bars!! and so far it seems like my signal isn’t dropping out like it once did.

  16. Marcus says:

    Hy,
    i put ios 5 in my iphone 4 preserve baseband 04.10.01
    with redsn0w but with Gevey Sim pro i cant unlock the phone part,
    Maibe i do something wrong?
    it just came a few second the signal but them it when away how can i do?
    thanks
    Marcus

    • Ace says:

      When you preserve your baseband, your iPhone isn’t jailbroken and so the sim isn’t activated. You need to upgrade your baseband first, then jailbreak.

      • Ace says:

        I apologize, I meant upgrade your iOS version, not your baseband

      • Marcus says:

        I mean i hade 4.3.5 jailbroken with baseband 04.10.01
        and gevey pro was working super….
        but them with redsn0w i upgrade my iphone 4 with IOS 5 preserving the old baseband 04.10.01 so now i have my iphone with IOS 5 but with gevey sim i cant get signal.
        so wats i should do exactly?
        thanks so much advance!!!!
        Marcus

  17. Marcus says:

    …and so i have now,
    iphone 4 with IOS 5 but the baseband is 04.10.01,
    and Gevey Sim Pro.
    You think that i can solv the problem?
    thanks

    • Ace says:

      You have to jailbreak it with the latest Redsn0w. Install Ultran0w and everything should be fine

      • Marcus says:

        ok thanks but forgive my last question but ultrasn0w will help me with baseband 04.10.01?
        thanks so much….im geting mad today

  18. Ace says:

    Ultrasn0w will only help you get rid of the “one signal bar” problem. You have to jailbreak so that the iPhone can recognize the sim card. I already unlocked my iPhone4 using the first generation of Gevey, with BB 04.10.01, so don’t worry :)

  19. Marcus says:

    Ultrasn0w…..install but nothing signal only 10 second and then away….
    thanks

    • Ace says:

      In my case, I didn’t wait to obtain the one signal bar, I just dialed 112, put the iPhone in Airplane mode and waited. You’ll maybe have to retry this process many times. Don’t give up

  20. Ace says:

    Yes Krishna, but after many many (many….) retries : Rebooting with Redsn0w, respringing…Then the signal appeared for just one or two second, and I continued the normal procedure

  21. Marcus says:

    Thanks Grande Ace!!!!!
    I won!!!!
    Look IOS 5 With baseband 04.10.01 i just take out my gevey sim and put a normal carrier and wopla i have the signal again and is working so well i did not expect and fast it came also the poup up of facetime.
    superrrr
    thanks

    • Ace says:

      You’re welcome my friend :) I really really hope that we’ll get an unlock soon, that would be nicer than Gevey :)

  22. Conor says:

    i have an iphone its not on my network and i want to update it to ios 5 and unlock and when untethered jailbreak comes out i want to jailbreak it

    should i update to ios with network it on then unlock with new ios 5 gevey.
    or

    unlock it then update

    after its unlock by either the 1 or 2nd way and an untethered jailbreak is released will it remove the unlock and if so can i just unlock it again and it will be fully unlocked with gevey and it will be both jailbroken and unlocked

    • Ace says:

      Conor, to unlock your iPhone with Gevey you have to verify your baseband, if it’s unlockable or not.
      You can go for a tethered jailbreak : Update to iOS5 with a custom IPSW then jailbreak. When untethered jailbreak will be released, you can do it over the tethered one, no problems.

      You will just have to do the “112/ Airplane mode” thing again.

  23. adriano says:

    My baseband is 4.11.08. Is it unlockable and until when? I’ve tried couple of options but unsuccessfully . Will there be any way to unlock it or will it be permanent?

    • Ace says:

      I’m sorry, the latest unlockable baseband by Gevey SIM is 04.10.01 You have to wait for an ultrasn0w unlock or a new type of Gevey sims. No ETA at the moment.

  24. Cornee Grefkens says:

    I would really like to warn people with the Gevey SIM.
    I am also using the Gevey SIM ( sinces one year ).
    I have a iPhone4 with baseband 02.10.04.
    After my update to IOS5 and installing all the Cydia apps I needed it didn’t work. Appsync 5+ was blocking the use og the Gevey SIM.
    My iPhone was jailbroken using RedSnow.

    • Ace says:

      There is no way this can happen. If it’s true, Saurik would have mentioned it. It works perfectly on my two iPhones (3GS, 4); no problems. Jailbreak with Sn0wBreeze and tell us what happens.

      Ace

    • Zorg says:

      I have 4.10.01 And I just updated to 5.0 preserving baseband update. After finishing, My first goal was check the Gevey. So Istill have all those option saying Accept or Cancel for unlock. One thing didnt show is,AFter taping Accept, I dont have 3 dots so I can call 112. Only No Service Message. Thats ok. just keep doig what need.

  25. Cornee Grefkens says:

    Didn’t try SnowBreeze yet. Was working on someone elses iPhone when I decided to update my own iPhone at the same time.
    I just found this out and wanted people to know so they can keep this in mind and avoid spending hours figuring this out.
    And believe me, it happend.
    I’d rather have AT&T unlock it but my contact in the USA says they will never do that.

    • Ace says:

      Do you have an AT&T contract? After one year it can be normally unlocked

      • Cornee Grefkens says:

        No, no contract.
        My colleague bought it for my ( Oct 2010 ) at an Apple store but I knew it had a lock.
        Thinking this would be easy to break but no way, just my luck

  26. Ace says:

    I suggest you to restart the same procedure over and over again (while preserving your baseband). While waiting for this unlock for almost a year, I wish you luck!

  27. xy says:

    Hi folks. I have an IPhone 4 in 4.1 and bb 2.10 jailbroken using greenpoison a year ago with a gevey sim. What happened was my sister accidentally reset all settings and all went f*cked up! I can still turn on my phone but ‘Settings’ icon was deleted and all apps (even not a jailbreak apps) closed automatically when clicked. Even messages and phone book. Any idea how can I fix this? Thanks everyone!

  28. Martin says:

    I’ve been trying to get my Gevey to work for hours and hours now, I have a valid AT&T card and a valid O2 card, after following these instructions perfectly, I still, cannot, for the life of me, get this damn thing to work! I’ve gotten the welcome message, dialed the 112, but when I get to the airplane mode step, it does nothing but whine “invalid sim” over and over again, it will not accept it.

    What is the benefit of jailbreaking the phone before I do this process? Do I have a greater chance this way?

  29. Rishi says:

    Hi, i’ve an iphone4, baseband 2.10.4, using gevey sim, but need to know, if i can update my phone to ios5 & would the gevey sim be able to unlock it ?
    If yes, do i have to buy aome updated gevey sim ? or the same would work..
    i’ll appreciate if anyone could reply..thanks…

    • Cornee Grefkens says:

      No need to buy a new Gevey SIM.
      Mine is working perfect with the iPhone4 BB 2.10.4.
      Just don’t install Appsync because then it will not work.

  30. evilgenius says:

    TinyUmbrella now preserves iOS 5.0.1. Can I go ahead and use this or I gotta stick with iOS 5 beta 7?

    I’m going to try this on my iPhone 4 bb 04.10.01 and will report the progress. But first let me know if its safe to use iOS 5.0.1?

  31. Zorg says:

    I have i4. 4.10.04, iOS 5.0 GM and app sync also installed , I use gevey , works very well

  32. evilgenius says:

    What version of iOS 5 did you use?

    • Zorg says:

      I took 5.0 ( 9a334) GM and used Snowbreeze whatever last version. Make sure when update from itunes, use only custom created BB from snowbreeze. Never use Itunes update, otherwise you will get baseband updated to 1 version. GL

      • evilgenius says:

        I’m getting error 3194 and its persistent. Any advice? What version of iOS did you updated from?

  33. Zorg says:

    Well. I am on 5.0 and I have same error when updating to 5.0.1 or even downgrading. I have read some posts how to fix, but they don’t work for me

  34. evilgenius says:

    My gevey ultra is now working on my i4 ios 5.0.1.

  35. RH says:

    IPHONE 4 WITH VERSION 5.0 (9A334) & MODEM FIRMWARE 04.11.08
    IT WAS WORKING ON GEVEY BEFORE UPDATE WITH ITUNES.
    ANY HELP?

    • Zorg says:

      There is no solution yet for 4.11.08. Before Updating to any firmware, read forums, posts, what baseband will be. You should update firmware using Snowbreeze.

  36. rockitup says:

    Hope you can help please, I have iPhone 4 still running 4.2.1 with baseband 3.10.1.
    There is a Gevey Sim Pro installed and I would like to know if I can preserve baseband and update to IOS 5.0.1 using the Gevey Pro.

    The guy at the store who installed the Gevey Pro before said it can only work with software up to 4.3.1 Maybe he is just saying that just to sell me the Gevey Ultra (inflated prices here in Philippines)

    Can any of you confirm if gevey Pro sim will work with this situation?

    If you have necessary links to the software needed it would be very helpful, I am running Mac but can get hold of a Windows machine if necessary

    Many thanks

    • Zorg says:

      My suggestion is. I have Very first one Gevey for Iphone 4 and It works on 5.0.1 with 4.10.11 baseband. So just in case save your Blobs via TinyUmbrella and upgrade to 5.0.1 via Snowbreze custom FW. not apple update. if Gevey dont work, you restore back to 4.3.1.
      Good luck

      • rockitup says:

        Okay, thanks for your advice Zorg. I will follow your suggestion.

        That helped put my mind at rest, I was worried being stuck on 5.0.1 without the Gevey Pro working
