GEVEY Sim Still Works on iOS 4.3.5

by Mahesh Kukreja · 59 comments

in Technology News

Apple seeded iOS 4.3.5 recently to fix Vulnerability Issues with Certificate Management. This update comes within 10 days of Apple’s last iOS update 4.3.4.

Now, for GEVEY Sim unlockers, here’s a good news. GEVEY sim works on iOS 4.3.4 as well as 4.3.5. Apple hasn’t updated iOS 4.3.5’s baseband and it’s still 04.10.01. Users those who don’t rely on jailbreak can update to iOS 4.3.5 and still use GEVEY Sim, GEVEY Pro & GEVEY Supreme. GEVEY Ultra will also work after you jailbreak iOS 4.3.5 with redsn0w.

Here are some screenshots:

The procedure for using GEVEY Sim, GEVEY Pro & GEVEY Supreme remain the same. Just dial 112 and turn the Airplane mode on and off. If you’ve any questions, feel free to ask below!

You must select “Boot Tethered” option in redsn0w. Then it’ll boot up properly.

You must select “boot tethered” option in redsn0w, then you’ll be able to run Cydia and your iPhone will boot properly.

Admin August 22, 2011 at 12:41 am


redsn0w provides untethered jailbreak for 4.3.3 and gevey ultra works fine on 4.3.3.


david August 23, 2011 at 11:32 pm

can we install cydia in 4.3.5 version and how?


ali August 25, 2011 at 6:49 pm

Admin August 25, 2011 at 6:56 pm


Please follow this tutorial to jailbreak & install Cydia on iOS 4.3.5


Iphone User September 2, 2011 at 4:55 am

The Gevey Sims will work on 4.3.5 IF AND ONLY IF you had a different version of software on it and manually upgraded yourself. The GEVEY WILL NOT WORK if 4.3.5 was shipped on your Phone…this is a fact. This is why some people can use it on 4.3.5 and some can’t. If you bought your phone with 4.3.3 on it and upgraded to 4.3.5 yourself…YES a GEVEY WILL WORK. If you bought your phone with 4.3.5 on it NO GEVEY WILL WORK. 100% TRUE. Don’t ask me why…it just is


jacky September 3, 2011 at 12:01 pm

hi, I got iphone 3gs with version 4.3.5 bb 5.16.02. can I use gevey sim for this? do I need to jailbreak before use gevey sim?
thank you so much


Admin September 3, 2011 at 4:52 pm


Unfortunately, GEVEY Sim is not available for iPhone 3GS. If you want to unlock your iPhone 3GS, you should update your iPhone’s baseband to iPad’s baseband.


Arg September 5, 2011 at 7:15 pm

My 3gs was on 3.1.2 and baseband 5.11.07 was jailbroken and unlocked, I reset my phone to factory settings and now my phone is stuck on apple logo. I do not have any shsh saved.
Can you gyide me what to do.


Admin September 5, 2011 at 7:57 pm


Which iOS firmware did you try to upgrade to? Try using iFaith (download from to dump your SHSH blobs.


Omar September 7, 2011 at 7:44 pm

Hi admin

Do I need to jailbreak my iPhone for gevey to work on it and unlock it?

I have iPhone 4 with 4.3.5 but dont want to Jailbreak it as its a tethered JB.

Does Gevey require Cydia?



kate September 13, 2011 at 1:37 pm

HI Admin-
I have 2 iphone 4s that i need to unlock to use in France. The first is ios 4.3.1 with bb 4.10.1 and the second has been upgraded to 4.3.5 on bb 4.10.1. Which unlock/jailbreak method would you recommend?


Saff September 13, 2011 at 3:38 pm

4.3.5 Jailbreak and Gevey Sim.

1 Jailbreak with Redsn0w. and firmware 4.3.4
2 Switch off and complete jailbreak in tethering mode
3 Pop Gevey Sim out after Iphone is Jailbroken.
4 Replace Gevey Sim… Follow Gevey Sim Instructions.

Gevey instructions.
1. Pop out sim. wait for No Sim message.
2. Replace sim, wait for Gevey Accept message.
3. Wait for the reception bar to show up. should only be one.
4. Dial 112. 2 seconds. hang up!
5. hit airplane mode off, then back on.
6. wait for you carriers reception bars to come up.
7 Your Done!

Eg. no need to turn phone off for Activation of Gevey Sim

My Iphone(4.3.5) is Jailbroken and Gevey Sim Running.


Sijaan October 21, 2011 at 7:25 am

YOU’RE A my saviorrr I love you !


sela September 15, 2011 at 12:51 pm

Hi admin, I have an iphone 4, 4.3.5 and I just ordered a gevey supreme sim. I want cydia on my phone also, but I heard supreme won’t work after I download cydia. Can I download cydia afterwards for it to work? What would you recommend?


Jresden September 21, 2011 at 2:19 am

How do I update my baseband for my 3gs 4.3.5, baseband 5.16.02 jailbroken but not unlocked iphone. I did not back up or save my shsh. It sounds like I can not use the Gevey sim….so what do you suggest my options are…or do I have a brick?


aja September 27, 2011 at 11:13 am

I have tried everything to get my phone to work. I recently bought the gevey ultra and I am not getting the welcome message. I have tried through jailbroken version with ultrasn0w and furiousmod. I have tried with manual version unjailbroken. I have tried taking the sim out and putting it back, and turning airplane, 3g, and roaming off and on together and individually. My sim did not need to be because it was already a micro. The only thing I can think of is I have a cracked screen but I have checked in the sim holder and there is no blockage; I don’t have to force the tray in/out. Any ideas of what I should do. Running 4.3.5 with 4.10.01 firmware with tmobile sim.


Atif September 27, 2011 at 9:23 pm

Hi Admin,

i bought new iphone 4, with version 4.3.5. For unlocking, kindly recommend me which Gevey sim i should buy? As the above discussion confused me which gevey sim will be ok. Waiting for kind reply. Thanks.


Eva October 12, 2011 at 5:13 am

Hi Admin,

I have Gevey Ultra and an iPhone 4 with the latest 4.3.5 software installed. I successfully jailbroke it using redsnow.
The problem now is: Gevey sim doesn’t seem to work.
I got the expected message saying to wait 15 sec, the dial 112, then hangup after 2 sec, then turn airplane mode on, then turn airplane mode off. I accepted the message then followed the instructions.
However, the “No Service” message is always there.

Any suggestions as to what I could do form here?

Thanks for your consideration!


shiraz October 16, 2011 at 8:09 pm

Admin October 16, 2011 at 9:01 pm

You will have to boot tethered using iBooty or redsn0w.


Paul October 19, 2011 at 10:48 pm

Hi there,

I’m new to using a gevey sim and just have a couple questions about it. I recently bought my friends AT&T iphone 4 (I was still on an iPhone 2g) and, to my dismay, found it was on 4.3.5 firmware (no untethered jailbreak available) and 4.10.01 baseband (only unlockable with gevey). So I bought a Gevey Ultra Sim and am waiting for it to come in the mail.

If I would like to use my phone for Tmobile and only a tethered jailbreak for 4.3.5 is available, is that okay? Can I just jailbreak it, activate the Gevey sim, and be good to go? Even though the jailbreak would go away after I turn off my phone?




Admin October 19, 2011 at 11:12 pm

Yes you’re good to go. Even if your iPhone restarts, you can boot in tethered mode to retain te jailbreak.


Paul October 19, 2011 at 11:32 pm

Thanks! I guess my next question would be do I need to re-jailbreak it each time I turn the phone on? Or will having an unjailbroken iPhone using the gevey sim still work with Tmobile?


Admin October 20, 2011 at 7:58 pm

No you don’t need to re-jailbreak. You just need to boot in tethered mode using redsn0w.


Paul October 20, 2011 at 11:47 pm

Woof. Rebooting in tethered mode every time I turn the phone on…That kinda sucks. Hope they come out with ios 5 untethered soon! With support for 4.10.01 baseband!


Jimmy October 29, 2011 at 7:55 am

But does it work? When I boot tethered (using redsn0w) with the Gevey SIM installed I just see an apple logo that never goes away. I never actually get to use the phone. I’ve got a jailbroken iPhone 4, iOS 4.3.5, Gevey SIM Ultra. If I take out the Gevey SIM I can boot tethered (and I see the pineapple boot logo instead of the apple), but then I can’t plug in my SIM and use it. It finds T-Mobile for just a second sometimes, but then it says the carrier was lost.


Admin October 29, 2011 at 1:44 pm

Did you try GSM sim other than T-Mobile & AT&T?


Parag Barjatiya October 28, 2011 at 10:09 am


Is the unlocking on 4.3.5 tethered unlock? Is this gonna give some issue if we use App store to download some application later on?



fanaa November 3, 2011 at 10:34 am

thank you


Mahesh Kukreja February 9, 2012 at 5:31 pm


Gevey sim isn’t available for iPhone 3GS.


sam February 25, 2012 at 11:10 am

Iphone 4, 4.3.5 and 4.10.1, is there any untethered software jailbreak available now? when I bought from someone, he upgrade to 4.3.5 from previous version, so I can use Gevey, why people mess with iphone and get stuck, which leave them with no choice but to upgrade to latest firmware.
