The Gevey SIM allows you to unlock your iPhone without the need of a jailbreak. The SIM card force activates the iPhone’s baseband by exploiting the emergency dialer function.

Apple released iOS 5 Beta 2 last night, and it appears that the Gevey SIM is now blocked from working in this second iOS build. It’s suspected that Gevey will try to battle Apple’s patching of its interposer while iOS 5 is still in the beta testing stages. 

MuscleNerd confirmed on Twitter that the Gevey is indeed blocked in iOS Beta 2, after numerous tips and reports surfaced about the issue. Apple most likely received pressure from carriers to block Gevey’s exploit.

It’s assumed that Gevey will aggressively update its unlock while it still can. For now, iPhone 4 users with a preserved baseband who want an unlock with the Gevey SIM will need to stay on iOS 4, or remain on iOS 5 Beta 1.

      i have beta 1, the original one, with using 112 to activate.. maybe only the ultra one is not working..?

      • c0edx

        He’s full of shit, I tried and it did not work.

    • Cadillaklova

      Dude if you really care about your unlock then stay away from any updates until you can confirm your unlock will work dumbass! You know what, just do it. Update to beta 2 right now!! Go for it!!!!!!

  • Hmmm…

  • Andres

    so is it working or not? I’m still on iOS4 but it would suck not being able to upgrade to 5 :[ I’ve the regular Gevey simcard atm Hopefully the Ultra is the only one not working 😉

  • that’s why I always buy an unlocked iPhone, so I don’t have to unlock it after that.

  • c0edx

    I’m on ATT, I’ll update to iOS 5 beta 2 and try the Gevey Sim. I’ll report back tonight and let you guys know if it still works.

    • Andres

      woot thanks!

    • c0edx

      Good news everyone, it works!!!!

      • Andres

        Wonder why people like MuscleNerd would say it wouldn’t. Which Gevey card do you have @c0edx?

      • c0edx

        I did not post the above message, I still haven’t tryed it yet. Please delet this person. I’ll let everyone know today when I try it.

  • c0edx

    When they first came out I got it for $75. I got it just to see if really worked. I’ll be home in like 4 hours and I’ll try it out. My wife has T-Mobile 4.2.1 with Gevey Sim so I’ll just use her sim to try it out.

    I’m confused; I thought the point of the Gevey was that it worked on some of the newer basebands. But the article says:

    “For now, iPhone 4 users with a preserved baseband who want an unlock with the Gevey SIM will need to stay on iOS 4”

    Do you really need to preserve your baseband to use a Gevey? This Redmond Pie post makes it sound like any baseband will work: http://www.redmondpie.com/gevey-ultra-sim-permanent-iphone-4-unlock-works-without-dialing-112-emergency-number-video/

    Just curious because I’m going abroad soon and thought about getting a Gevey.

    • Read! “Apple released iOS 5 Beta 2 last night, and it appears that the Gevey SIM is now blocked from working in this second iOS build. “

      • Massie

        Yes, but my question is whether iOS 4 users need to preserve an older baseband. Because the article I linked to suggests you can use any baseband with iOS 4. I wasn’t asking about iOS 5 at all.

    • Joe

      I think they just meant anybody wanting to use gevey should stay on some version of iOS 4. I don’t think the baseband matters w gevey.

      • Massie

        That’s what I thought too; maybe the article is just phrased in an odd way.

  • You could just buy an unlocked phone. Then use whatever sim you like

  • Gary

    ChaQanZ is an asshole 🙂

    • Andres

      he is, indeed. I had my hopes up…

  • c0edx

    Okay guys, I just updated to iOS 5 Beta 2 Baseband 04.11.06 and the Gevey Sim DID NOT WORK. It gave me the warning message then the singel signal bar, I dialed 112 and hung up then I turned Airplane Mode On. After I turned it off there was no signal bars, the top left was completely empty it keep giving s Sim Failure error. So their you have it it’s patched. So the last baseband it worked on was 04.10 iOS 5 Beta 1. Now I can’t confirm if you preserve your baseband and then update to iOS 5 Beta 2 that it will work. I would not recommend anyone doing this.

  • Alfredo

    I can confirm the gevey sim works!! if you preserve your baseband and then update to iOS 5 Beta 2. I used Sn0wbreeze beta 3 to preserve the baseband. The only problem I had is when i reboot the iphone, the screen dont pass from the apple logo, after that I should put muy device in DFU mode and run the ibooty and then works.

    • Cadillaklova

      So pretty much you have a tethered jail-break with a preserved baseband on iOS 5 beta 2?

  • Hi everyone.

    I can verify and send Printscreen that the first Gevey SIM works on iOS 5 beta 2 with baseband 02.10.04, although it has the one signal bar issue. Despite that I can make and receive calls, SMS’s, MMS’s and Personal hotspot also.

    I used sn0wbreeze to build the custom firmware and preserve the baseband, and iTunes 10.5.0.43 to restore. After that had to use SAM to activate, and then Gevey SIM to do the unlock.
