Yesterday, Apple released iOS 4.3.5. The update fixed a security vulnerability with certificate validation. If you jailbreak and use UltraSn0w, stay away from this update. But if you are a Gevey SIM user, we have some good news.

Even though we previously reported that Apple blocked the Gevey SIM in iOS 5 Beta 2 and above, the Gevey SIM works with iOS 4.3.5…

Now it seems that this might be the last iOS 4 update, and Apple might leave the exploit until the final version of iOS 5 is out.

If you don’t know what the Gevey SIM is, you can learn more about it here. It has also been confirmed illegal by MuscleNerd.

What are your thoughts on this? Do you use the Gevey SIM? Tell us in the comments below!

    so to use this i gotta.. tethered jailbreak iphone operation system 4.3.5.. then install the required repo… but do i have to stay jailbroken dor the unlock to wokr or i can just get a clean restore and it would still work?????

  • Tom

    I just ordered mine a couple days ago as I’m under baseband 02.10.04 and it’s unlikely we’ll get an unlock by the time the iPhone 5 comes out. I’m still on iOS 4.3.3 as both .4 and .5 do not allow untethered jailbreak.

    But the reason for my comment is something you’ve been saying twice in recent posts : “it has also been confirmed illegal by MuscleNerd.”
    MuscleNerd was refering to ‘dialing 112 then hanging up’ as being illegal, not the use of the Gevey Sim itself. The new version of the chip does not require to dial 112 anymore. While it doesn’t confirm that its use is actually legal, I just wanted to point out that your comment wasn’t completely true 😉

    Still love your blog!

    Gevey Ultra is not illegal. Gevey ultra is the best one.

    • The SIM itself isn’t illegal. What is illegal is to dial 112 here in the US. It’s like calling 911 and hanging up on them. Law is different in each country, but dialing 112 and hanging up is definitely illegal in the US.

    I want to order Gevey SIM card here in Croatia but I don’t know if there is a new card every time when new software came out or the same card can unlock all new version of software?

  • Tbv

    Dialing 112 and hanging up within 2 seconds, the call does not even connect. It is not illegal. I did this procedure at least 20 times, and the police is not knocking on my door nor am I banned by T-mobile. It is not illegal if the call does not connect.
    I understand this is not the best method, but it is the only method available. Even the Gevey Ultra dial 112, it does so in the background in order to unlock the iPhone 4 also.

    The new Gevey Ultra does not dial 112:

    To Francesco: you can use the untethered jailbreak on 4.3.3, no need to update to 4.3.4 or 4.3.5. As far as keeping your phone jailbreaked, my guess is that you have to as you need to install an app once you have added the repo.

    To kreso2105, there isn’t a new card for every new software. You have 2, one that requires 112 and one that doesn’t (the Ultra, which is the one I would suggest). The last one works with most firwares up to 4.3.5 (even the earlier beta iOS 5 ones), but as mentionned before I don’t see the point of updating to 4.3.4 or 4.3.5.

    My card should arrive today or tomorrow so I should know more soon.

  • if you dialed 112 in my country, no one would care. you’d be lucky if someone answered on the other side. lol!

  • mikelite

    I used a Gevey for the last two weeks in SE Asia & it was great. It’s not true plug & play, but the directions are clear & it always worked. And the whole 112 thing is misleading. You don’t actually have to connect. In my experience, 2 seconds barely got the phone past “connecting”.

  • Fred

    Can somebody please confirm that it actually works on 4.3.5? I tested it both ways; automatic (tethered jailbreak via ultrasnow and had furiousmod deb installed) and manual 112 dialing nothing wroked. Anyone else experiencing this? I know the sim is not defective because it works on my other iphone4 that is still on 4.2.1

  • Fred

    Correction: I meant Redsn0w 0.9.8b4

  • Fred

    Update: After two days of seeing failure message, my ultra Gevey is finally working. The T-mobile status bar magically appeared. So folks I guess it works on a freshly restored iphone 4 on 4.3.5 but may be unstable at times.

    • Greg

      I had the same problem too! I worked for a couple of hours trying to get a JB 4.3.4 to work with the Gevey Ultra, no success. I tried a JB 4.3.5 and in both case, it just ultimate comes up and shows NO SERVICE. The only way I could get it to work, was stock iOS 4.3.5 and do the manual process to bring it up and that works, but that leaves me no where on being able to configure the internet/MMS probperly for TM.

  • Ehab

    I’ve got the Gevey pro sim, I’m so not sure about the price, gotta feeling that I was cheated. Any ideas?
    And are the complains about the weak network coverage from the Gevey sim users true?
    What other drawbacks does it have? Which is the latest Gevey sim?

  • rami

    does everytime i reboot my iphone i have to do all of this again?

    • Ehab

      Well.. respring doesn’t affect it sometimes, but rebooting does occasionally =/

    Yay gevey ultra works for trinidad finally i can use my phone.. tested date 9.9.11, running ios fw 4.3.5 ,modem fw 4.10.01, Tethered jailbreak with redsnow, for people who have been having problems like me NO SERVICE, after you install furiousmod package from cydia - remove your sim, reboot phone, while your waiting for your phone to start with the pineapple logo as soon as you hear your phone beep put in your gevey ultra and sim, give it a few seconds, you should see a welcome message pop up press accept, your phone should go through the whole process automatically press ok when you see no sim installed and it will show full signal bars in a few seconds or so, do not bother with dailing 112 or airplane mode leave the phone let it do the stuff automatically, for those who are Tethered jailbroken on redsnow like me try this, i hope i have helped someone.

    -you must get welcome message and accept it
