How To: Unlock iPhone 4 With Gevey SIM Card On iOS 5 Firmware

If you have an iPhone that is unlocked using the Gevey SIM card running iOS 4, chances are you want to upgrade to the official iOS 5 firmware. The question I am sure you are asking yourself right now, however, is can I upgrade to the iOS 5 firmware and still unlock my iPhone with my Gevey SIM card? The answer to that question is Yes, but you cannot just simply update to the stock iOS 5 firmware. You are required to make a custom iOS 5 firmware using a Jailbreaking Tool such as Sn0wbreeze or RedSn0w.

Gevey SIM Card Unlock iOS 5

How Do I Unlock My iPhone On The iOS 5 Firmware?

First things first. If you are new to the unlocking scene you are probably wondering how one would go about unlocking their iPhone on the iOS 5 firmware; The answer is simple. You can either use a software unlock called UltraSn0w by the iPhone Dev-Team or a hardware based unlock called Gevey SIM card by Apple n Berry. The difference between a UltraSn0w and the Gevey SIM card, however, is that UltraSn0w only supports a limited number of older basebands while the Gevey SIM card supports a limited number of newer basebands.

Note #1: The Gevey SIM card works with the following iPhone basebands:

  • 01.59 – 02.10
  • 03.10.1 – 04.10.1

Note #2: UtraSn0w supports the following iPhone 3GS/iPhone 4 basebands:

  • 4.26.08
  • 05.11.07
  • 05.12.01
  • 05.13.04
  • 06.15.00  (Special iPad Baseband)
  • 01.59.00

If you are looking to unlock your iPhone on the iOS 5 firmware you will need to see which method of unlocking will work with the baseband currently running on your iPhone.

Can I unlock My iPhone 4 with Gevey SIM Card on iOS 5?

As I explained in the intro paragraph, if you have an iPhone 4 that is currently unlocked with a Gevey SIM card, you can unlock your iPhone on the iOS 5 firmware with the same Gevey SIM card as long as you preserve your baseband while updating to the iOS 5 firmware.

How Do I unlock my iPhone 4 on iOS 5 with Gevey SIM card?

If you would like to proceed and unlock your iPhone 4 with a Gevey SIM card on the iOS 5 firmware you will simply need to follow our in-depth guide on updating to the iOS 5 firmware without updating your iPhone 4’s baseband in the process. This is a relatively simple thing to do and involves using RedSn0w. The only downside to this guide is that at this time only RedSn0w 0.9.9b5 can create a custom IPSW to preserve your iPhone 4’s baseband. The reason this is a downside is because RedSn0w 0.9.9b5 is only compatible with the Mac OS X operating system at this time. Meaning if you are a Windows user you will need to use Sn0wBreeze to preserve your iPhone 4’s baseband while updating to the iOS 5 firmware.

After following the how to guide shown above you can proceed to setting up your Gevey SIM card on the iOS 5 firmware.

In case you forget how to setup your Gevey SIM card on the iPhone 4 you can watch this instructional video embedded below…

    I have a problem with the WI-fi.It’s grayed and i can’t turn it on or off.Is there any fix to it?Also most of the time the camera’s shutter won’t open.PLease HELP! iOS 4.3.4. Iphone 4.

  • FARP Thor

    Now that I upgraded to iOS 5 and didn’t JB it, I lost the fix for the caller id (UIMobileCountryCodes.plist).

    Is there anyway to workaround it? I mean, is there a way to access this file without jailbraking? Or, can I JB, fix the file and un-JB it?


  • Sohil

    i have already update my iphone 4 on ios 5 and my gevey sim not working on it
    is there any way to start my phone again to work with gevey ???/

  • Ian Sweeney

    I have an iphone 4 with bb 04.10.01 and ive updated to ios5 using the
    custom ipsw (the same as you) but my gevey sim still wont unlock my
    iphone. I have tried doing what you have done but when i go to phone
    and then to sim applications, the gevey bit isnt there like yours. mine
    just says location then options for get information, get imei and get
    network measure. No gevey sim options come up like yours. can you help
    me please?

  • Amit

    even i did the same thing..i found out it’l take 10-15 days for the unlock to come out..till then use iphone as ipod..if i get to kno any other way il let yu kno..n u too do the same..

  • FARP Thor

    What you guys need to do ASAP is to restore your iPhone to the 4.3.5 version. Do it while apple stills sign this version, is the only way to restore to baseband 4.10.01.

    When you finish that, you can use redsn0w to build a custom no BaseBand update to iOS 5.

    I did this mistake yesterday and was able to revert.

  • phoene

    some says yes some no.. what shall we do!.. this is bad. snowbreeze isnt helpful.. and redsnow still not available for windows..  still wont unlock..i hope apple will have unlocked iphones so we can just update anytime we want..pbbft!!

  • Diego

    I already downloaded the 4.3.5 ipsw but don’t know how to make the downgrade using itunes…any help??

  • daniel perez

  • Amerhot77

    its realy work man

  • FARP Thor

    Ok, I JB it after all, so I could fix that calling id issue. The problem now is that I’m unable to connect to any network. Is Gevey compatible with iOS 5 WITH Jailbrake? Should I need to install anything else?

    I preserved the BB.

  • Ptw6656

    I have downgraded my firmware to 4.10.01 and used sn0wbreeze to upgrade to ios 5. Is there any way to jailbreak my phone now?

  • KBBb

    hey sorry I dont understand much about jailbraking or downgrading. In fact, I updated my iphone 4 to ios5 after a source told me that the gevey sim would work, to my surprise my phone is now useless.
    The only thing i can thing of at the moment is to downgrade to a previous version. I have tried restoring however it automatically re installs the ios5 without letting me choose a version.
    What would be the best way for me to downgrade to be able to use my iphone? If not, if I sync to an older laptop where i have not downloaded ios5, will it work? thank you

  • Cherian Jitin

    I have followed the steps mentioned and I have preserved my BB to 4.10.01 on iOS 5. However, whenever I try doing the steps required for Gevey SIM, it does not identify the network. It does give the error or invalid sim and no sim however, after all the painstaking effort all it shows is No Service…. Please help

  • Enchantinspellz

    switch on ur fone wid da gevey sim… once u get gevey msg … accept it! nd in ios5 u don get a signal.. it starts off wid searchin nd den u get no service.. now once u accept da gevey msg nd no service appears… immediately call 112 (make sure ur call goes thru if it says call failed den call 112 again) hang up within two seconds… den go to settings nd toggle airplane mode on n off… u get sim failure prompts but also da carrier appears nd it starts searchin! within 15 seconds or so ur signal will appear.. ur phones unlocked!

  • Madgreen77

    I used redsn0w it gives you step by step instructions

  • Madgreen77

    Yes you can jb it both pc and Mac

  • Madgreen77

    You need to put phone in DFU mode using redsn0w then if you are using a Mac hold the option key or windows hold the shift key and click restore select the ispw you want if you haven’t saved one google it and download 4.3.5

  • Karthik

    Cool… is working now….I have upgraded my iOS from 4.2.3 to 5 using sn0wbreeze and after all my phone is unlocked using gevey sim. No issues at all. Thanks for your post.

  • Carlosagmejia

  • Carlosagmejia

    Amit? 10-15 days for the new gevey unlocking ios5???

  • Madgreen77

    sorry not general go into the phone setting and at the bottom is sim application

  • Madgreen77

    downgrade to iOS 4.3.5 quick before apple stops signing it and then do a custom install following the instructions you can find doing a search and you will have your phone working you will need redsn0w

  • Madgreen77

    no reboot it with the tool in redsn0w this is what i did or try again if that does not work then you will need to downgrade iTunes 

  • Kinggs23

    ok so i have a gevey ultra sim and it does not download the furious mod from cydia how can i make the gevey ultra work i have ios 5 and baseband 4.10

    I have repeated the process numerous times n i have ios5 with 4.10.01 with ultra gavey is there another option or another way i can possibly try???? 

  • Kinggs23

  • Patrik

  • zerocool

    I had the same problem, I tried to downgrade using itunes from my friend but did not work either, do i went to a iFix shop. I did not see what they did to the phone but now i have iOS 5. Cannot use my SIM but i have wifi at least… 

  • Dyalmaguer

    how the hell do you have facetime on t-mobile? niceeeee

  • FARP Thor

    I’m sorry to say, but apparently Apple yesterday stopped signing older basebands, meaning now you are left with a fancy iPod.

    If I were you, I would bug Gevey to somehow fix this and complain to AT&T (provided your iPhone was from them) about their never unlocking policies.

  • Alvin Tran

    Mine always says searching, then no service. Then searching again, then no service. And the carrier tab is there. Help.

  • von

    here’s an easy step.
    1. Press “Accept” on Gevey sim message
    2. “Searching..” will be displayed then “No service”
    3. Dial 112, hang up for 3 secs
    4. Turn on Airplane mode
    5. Prompt will appear! Do nothing until the phone goes to sleep.
    6. Open phone then turn off Airplane mode.
    7. Select Ok on all prompts.
    8. Turn on Airplane mode again then leave it for 15 seconds.
    9. Turn off Airplane mode.
    10. ching!!! there should be a signal! :)

  • Walataza

    No signal

  • von

    after step 4, “No sim blah blah” will be displayed. don’t do anything when this prompt appear. wait for the device to go to sleep as stated in step 5

  • Alana0mc

    what do i do if i already downloaded the ios 5 without preserving my baseband???

  • leopardi

    HELLO. i was already using my unlocked phone with the gevey simcard. then by mistake upgraded to IOS5. now in the welcome setup it doesnt let me proceed because it detects a simcard thats not valid…im in another country so…getting a sim card from at&t wont be an option. will redsnow work? if not. is there something i can do?

  • Maryam

    how do you downgrade to iOS 4.3.5?

  • Maryam

    Did you just use the instructions from this post? Who is your provider? I’ve been trying to unlock my iPhone 4 that I upgraded to iOS 5 but I’m with T-Mobile so this upgrade was a pretty bad decision on my part.

  • Pratikarya666

    hey how did u downgrade ur firmware to 4.10.01…..plz help plzzzzzz

  • Pratikarya666

    did u get ur problem fixed….?

  • MyFizzy

    Holy crap!  This actually worked for me using a $3 Gevey SIM on eBay!!!
    It took me a few tries to get it working though.  Here’s what I did to get it working:Follow the instructiuons exactly in this tutorial video.  Thew only thing I would add is:After you accept the pop up SIM message, wait “15” seconds before you dial 112.Thanks!

  • Maryam

    You did this for your iPhone 4 with the iOS 5 update?

  • Vishal B Kumar

    I somehow managed to install iOS 5, keeping my baseband 3.10.01.First of all when I inserted the gevey + carrier sim, I got the accept message, but after accepting the phone shows only no service message and nothing else(unlike the single bar earlier). But then also I dialed the 112 and managed to get connected to my carrier.But although i get the complete signal.. I am unable to place calls shows call failed(sms fails too!)! Any solutions?? i am using the old gevey turbo sim.?

  • MyFizzy

    Try this:

    “Reset Network Setting”    (Settings -General – Reset)

    Follow the instrcutions in the video.  After you accept the pop up SIM message, wait “15” seconds before you dial 112.

    Good luck!

  • Steve

    Quick question.
    My iPhone 4 is on ios 4.3.3 and baseband 03.10.01.
    I rely on my Gevey Sim to unlock the baseband.

    So if i wish to update to ios5.
    I have to preserve my bb using redsnow?

    So basically, if i update to ios5, keep 4.10.01 i should be fine right?


  • Bwatson2006

    Yep – same firmware as me and working great. I had to put my iPhone in dfu mode in order to accept the custom firmware but working great!!

  • Bwatson2006

    You need to downgrade your baseband but I don’t think it’s possible. I may be wrong though.

  • Topklassjoadz

    i did the same thing and I am currently waiting for a solution

  • Kserranogo

    I had the same problem, but i cannot make work my iphone neither like a iphone, because the screen says only compatlble SIM cards…. how u made it work as an ippod?

  • Chauncy_mack

    Question:  My iPhone was never unlocked or jbroken at 4.3.5, I used redsn0w to create custom ipsw with preserved 4.10.01 bb to iOS5 and applied it to the phone.  I stick Gevey Ultra in with T-Mo SIM and the phone continues to say No SIM…. did i do something wrong?

  • Maryam

    when i click on sim applications i dont see the screen that you have on the video i see Location: Get information, Get IMEI, Get Network Measure. What do i do?!

  • Maryam

    And I get the Carrier thing too but i’m not getting the signal.

  • Andyweak

    Mine did the same thing…for a week. ugh. Then I went into cydia and deleted ultrasnow…and rebooted following the gevey instructions and then it worked!! 

  • Peddi73

    Hi, im from india and it says no sim card inserted and it doesnt even let me go to home page . i have to call 112 and try to get to home page and wen i went into settings in phone there is no “Sim APPLICATIONS” i can see SIM PIN but no sim applications,Help?

  • brainware


    I’m using iPhone 4, iOS 5, with BB 4.10.01, and using Gevey Ultra.

    The problem is when I try to install Furious Mod from Cydia, It’s says:
    Sub-process /usr/bin/dpkg returned an error code (1)Configuring FuriousModConfiguring FuriousModsubprocess post-installation script returned error exit status 1

    I already try many times, but still have same error. That’s why I must downgrade to iOS 4.3.3 again :(

    Does anyone knows the problem and the solution for this?

    Thanks a lot,

  • Hillelschreibe

    i did the same mistake.. but i actually had the original sim that came with the phone.. it then let me proceed and everything and i even got to the pont where to dial 112 and it worked but it never found the sim after that… so HELP what cani do if i mistakenly upgraded from 4.3.5 to 5.0 without saving anything first????

    If you don’t get the language option, just take out the sim while the phone is on and put it back in, you should get the message. I had the same problem.

    if you’re using the gevey sim– when you switch on airplane mode for the second time leave it on for 30 seconds rather than fliping it on then immediately turning it off.

  • Dimentianon_hazardous

    Hello, i have and iphone 4, with iOS 5 and baseband 04.10.1. I want to unlock it with gevey sim but i have some problems. The first thing is that since i have jailbroken it with redsn0w i cannot turn off the phone because it is tethered, so i need to use redsn0w just to turn on the phone. So i want to know if is there a way to unlock it without turning off the phone. Anyway, i turn on airplane mode and then off, and the message of gevey shows up. I wait for 15 seconds until it says “no service” then i dial 112 and just after i hand off after 2 seconds it shows a message “no sim card installed” i click ok and then i go to turn airplane mode on, and then off, it goes “searching” and ends again with “no service” that, over anf over again.. and i cannot get my iphone unlocked. I need help

  • Ryan

    I had the same issue as yours.  To fix it, you need to install semitether from the bigboss repo.  The new mobile substrate that was installed with the package fixes the incompatibility with gevey

    sorry there is no way to downgrade baseband. the only thing you can downgrade is firmware, but that would only help for jailbreaks.

    Hi All,

    The ultrasn0w is use to the sim doesnot gets unlocked.

  • Ed

    Now apple sucks since i want to buy new iPhone 4s but i still have iPhone 4 in perfect condition with ios5. If i buy new i put this in the shelf useless, would like to end my family in Europe but they would not be able to use it since it is locked by the carrier, apple should make it possible to do unlocks for additional fee. That’s just pisses me off, want to buy a new and keep your old one useless. Just a thought.

  • upyoursapple

  • Kamau Wanjohi

    Hi, I have the same problem, I updated to ios5 using iTunes and now I cannot use my Gevey SIM. Has anyone found a solution to this?

  • Andresyanez

    To everyone that updated their phones with iTunes without preserving baseband will be stuck there until some other method of unlocking comes out. The only thing you can really do is not update the phone any further in hopes hackers will catch up until the iOS you have at the moment.

  • Jennefer3

    same thing happened to me…did you find anything out on how to fix or reverse it?

  • Kamau Wanjohi

    From what I’ve read, there’s nothing you can do. Have to wait for hackers to figure it out. Meanwhile, don’t update your iOS.

  • No0user


    Iphone 4 / baseband 02.10 / redsnow jb / semitether bigboss / ultrasnow / gevey ultra from applenberry
    0. Run jb/ install semitether/ install ultrasnow
    1. reset network settings
    2. reboot tethered
    3. accept gevey msg (wait until you see no service)
    4. dial 112 and Hang up after 2 secs
    5. flip airplane mode

    Without ultrasnow you get only one bar for a carrier signal.

    i also have 4.11.08 on ios5 i want to know how to downgrade as well

  • Haoly2000

    Hi Ed, Now Apple store they sell unlocked iPhone 4s for real. Go to Apple web side, search for iPhone 4s unlocked and you will be happy.

  • Guest

    Your problem is most likely that you did not preserve your baseband. The current baseband version in iOS 5 cannot be unlocked using a Gevey. 

  • Nikhilesh Patil

    i had updated to ios 5.0.1 with preserving my BB to 4.10.01 using gevey but m not able to see little E logo for GPRS, iPhone with internet is crap can anybody over here tell me how to get that work?? SOS!

  • Nikhilesh Patil

    I had updated my iPhone to iOS 5.0.1 with BB 4.10.01 unlocked with Gevey, everything went well except the fact that i m not able to see little symbol E for GPRS, iPhone without GPRS is crap… can anybody over here tell me how to get that work? FACETIME AND iMESSEAGE is working on iOS 5.0.1 :D

  • Nikhilesh Patil

    is your gprs working?

  • Nikhilesh Patil

  • Omgnisha

  • kev

    day folks,

       I have
    scan through the info here and didn’t see any questions on iPone 4s.  Now I may have missed it and if so, I’m

    I have a iPhone 4s ver. 5.0 BB 1.0.11 and it is locked to Rogers and I
    use Koodo, I wish to unlock it and I have heard that the Gevey Sim is one of
    the best ways.  So far I have not found
    any information on the 4s running 5.0. 
    So my question is;  is there a
    Gevey Sim for my iPhone 4s ver. 5.0 with a BB of 1.0.11?


    Much thanks for any help here

    How To: Unlock iPhone 4  SIM Card On iOS 5 Firmware 04.11.08…. pleas  pleas im in iraq

  • Rajitha_ks

    turn off 3g, cellular dara and dara roaming before activating. it worked for me.
    after activating with gevey sim you can turn those on.

  • Mtncrossdad

    I have cut my sim card to fit and have it on top.  Is this right? 
    I then start up my iphone 4 and it says different SIM detected.  Please connect to itunes.  I can’t get it to go to the page to ‘CANCEL’.  WTF.  Anyone able to help?!!

  • Mtncrossdad

    Type your comment here. Should I be using a new SIM card?  T-Mobile…
    Does anyone know?  I was using my old SIM card.

  • Catch

    Running through this tutorial (have NOT updated my baseband). Every time I get to DFU mode it says that DFU failed and I am now in recovery mode instead. Any suggestions?

  • MyFizzy

    Yes Maryam Joon. iPhone 4, iOS 5

    But I preserved my baseband 04.10.01.  This is crucial if you want to use the Gevey card.

    Good luck!

  • Nilnil23

    u ve backup of ur ur old ios???

  • Vasquezcrismely

    where can i buy the gevey  whats store

  • Wafafe_1

    How can I unlock my iPhone 4 with 04.11.08?Please help.  


  • Leroidunoir

    hey every body u should know that if u use redsnow u will likely update your base band, this article is wrong wrong wrong…. PWNAGE TOOL is the one that keeps your base band from upgrading when you switch to the new iOS.
    I’ve been a unlocked from long time now and i know what I’m talking about

  • MyFizzy

    check on eBay for Gevey Pro Turbo Sim For Unlock iPhone 4 4.1/4.2.1/4.3.3

  • MyFizzy

    Don’t buy there expensive ones. I paid $3 for mine!  You need to preserver your baseband if you’re planning to upgrade to iOS 5.

    If your baseband is anything over 04.10.01 , the Gevey SIM will NOT work.

    Good luck!

  • MyFizzy

    Unfortunately there is no way to unlock your iPhone with this baseband.  Sorry!

  • MyFizzy

    You’re WRONG!

    I upgraded to iOS 5 and preserved my baseband with redsn0w 0.9.9b5 

  • Alvin Tran

    Does Gevey Sim drain battery? Because Gevey SIM seems to be the only cause of battery drain on my iPhone 4, no jailbreak apps installed. Few apps running on background. Many people say that their phone runs for 48 hours with heavy usage, but mine barely even make it through half a day. (It sits in my pocket when I’m at school for like 7-8 hours, only surfing the web, checking emails, and all that until around 8 when I have to plug it in. No 3D games, no game at all, no 3G, nothing that drains battery fast except for surfing web) So does Gevey SIM drain battery?

  • Dadw

    you should switch on roaming :)

  • Chetans303

    please help

  • Seduction_for_ever

    hey guys, i use iphone 4 with BB 04.10.01 with a gevey sim supreme

    does this affect the procedures?

  • Seduction_for_ever

    Btw my iphone is on 4.3.5 and i want to upgrade to ios 5

  • Chetans303

    does it work on iphone 4 , ios 5 , with baseband 4.11.08 ?? 

  • Ducquyle

    That method above worked but so did the old method.
    I followed his method and only worked for me once and I tried it again and did not get any result.
    While following his video, instead of turning on and off, I just turned on airplane for 30 seconds until “Sim failed” or something about the Sim popped up and turned it off and it worked. I tried it twice and was able to get the same result.
    Just follow his video and replace the turning on and off with the old method.

  • Youssef_r-man

  • Yoosha123

  • iPRO

    I have a question, after I restored my iPhone and I’m in the midst of activating the phone again, it seems that the gevey sim card is not acceptable.. I am receiving this message on the last part of my activation:

    “SIM not valid: Only compatible SIM cards from a supported carrier ma be used to activate iPhone. Please insert the SIM card that came with your iPhone or visit a supported carrier’s store to receive a replacement SIM card. ”

    Kindly help. TIA!

  • gevey

    if you’re using the gevey sim–after 112.. go in settings switch on airplane mode..leave it on for 30 seconds rather than fliping it on then turning it off.

    I brought an unlocked gevey sim iphone 4 to the US and want to use it with AT&T. The seller informed me that the iphone 4 was originally bought from canada, and hence, it’s original carrier is not AT&T. If I try to use the phone without the gevey unlock sim, is it possible that my AT&T sim will activate the iphone 4, even though it was not originally locked to that network?

  • Nenapuka87
