How To: Unlock iPhone 3GS (04.26.08 – 06.15.00) On iOS 5 Using UltraSn0w 1.2.4

If you are hoping to unlock your iPhone 3GS on the official iOS 5 firmware you are in luck. The Dev-Team have released a new version of UltraSn0w (UltraSn0w 1.2.4) which supports unlocking the following basebands:

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

To find out if you have one of the basebands specified above you will need to go into the Settings.app > General > About and look for the Modem Firmware field. If your iPhone 3GS is running one of the baseband specified above you can successfully unlock your iPhone 3GS on the official iOS 5 firmware. Continue following the how to guide below to learn how to unlock your iPhone 3GS on iOS 5.

Note: In order to update to the official iOS 5 firmware and still preserve your baseband so it is unlockable, you will need to follow our in-depth how to guide by clicking here. DO NOT under any circumstance update to iOS 5 or you will update your baseband in the process. You will need to create a custom IPSW through RedSn0w or Sn0wBreeze (click here for more info).

Unlock the iPhone 3GS on the official iOS 5 firmware

Step 1) - As we noted above you must already be running the official iOS 5 firmware on your iPhone 3GS (click here if you are not), and you must also be jailbroken on iOS 5. If your iPhone 3GS is not jailbroken please click here.

Step 2) - After your iPhone 3GS is running the official iOS 5 firmware and is jailbroken you will need to simply launch Cydia from your SpringBoard.

Step 3) - Once Cydia is up and running you will need to go into the Sources page. To go into the Sources page tap Manage followed by Sources.

Step 4) - Typically, the UltraSn0w repo is included with Cydia. If not, tap the Edit button followed by the Add button and you will be prompted to add a URL source. Type:

http://repo666.ultrasn0w.com

Followed by tapping the Add Source button.

Step 5) - Cydia will automatically refresh and update sources.

Step 6) - After Cydia is done refreshing sources. Tap the Search tab on the bottom tab bar and search for UltraSn0w. Once UltraSn0w appears, tap on it and you should see version 1.2.4. Read through the description and tap the install button to install UltraSn0w 1.2.4 to your iPhone 3GS running iOS 5.

Note: In case you are not familiar with UltraSn0w, it is a software unlock for your iPhone 3GS meaning you can use your iPhone 3GS with any carrier by simply inserting the SIM card.

Step 7) - When UltraSn0w is installed you must restart your iPhone 3GS and run RedSn0w to boot tethered, you’re done!

Your iPhone 3GS should now be fully unlocked running iOS 5. Let us know if you have any questions in the comment section below…

    Hi,

    first thanks for the great work !

    I have a 3gs which has been upgraded to ios5 via itunes. Going through the activation process, I got stuck. I the realized that the second had iphone I bought for my wife was unlocked and that I probably locked it with the upgrade.
    After 5 hours of web surfing (knew nothing about iphones, I don’t use one…), I could jailbreak with redsn0w. I could use the 3gs but no carrier was found while the sim car was inserted. I then installed ultrasn0w to unlock it and booted with redsn0w. I have red the step by step very carefully and everything went according to the description but I still can’t find any carrier, it’s like if the sim car is missing. My baseband is 06.15.00.

    Any idea what could have been going wrong ?

  • alexgee

    I managed to get it jailbroken and downloaded the ultrasn0w. after rebooting the network option comes up in my settings but i do not see any carriers to choose from!

    I sent u a message, it’s waiting for approval :)

  • Portalbr

    Re-flash your baseband using latest version of Redsn0w. Follow the instructions (it’s via the Jailbreak option) and don’t interrupt the process. Finally after it’s done, boot up as per normal tethered method.

    When it was upgraded to ios5 it  simply froze! But with redn0w jailbreak I was able to make it work again. The BIG problem now is that it is not able to find a carrier not matter what I do :( And it doesn’t even ask for the SIM card, and I am not able change those settings.
    My baseband is 06.15.00.

    Please, can you help me fix it?

  • DeeDreMusic

    same here!

  • DeeDreMusic

    I did everything exactly how instructed and still it didn’t work. I can’t make no calls or anything!

  • Rbenitezz

    Hi, I had the same problems, but I fixed now! I have a 3gs 6.15.00 unlocked with t-mobile . First I made the mistake to upgraded to iOS5 with I tunes 10.5, then I jailbreked and unlocked, (several times and in different ways) but doesn´t find the carrier (no signal). Then I find the answers here, I download snowbrezze in the link in this page and the iOS 5 in here in this page too. Made my custom iOS5 file and install it. Did not activated, then I use redsnow to jailbrek it but i figure that probably my baseband has something wrong (6.15.00) so, when you choose to instal cydia, I also chose install iPad base band (6.15.00) To se if that fix it. After that The pineapple runing, but it takes a little bit longer, and then ultrasnow in the iphone. All the time with the t-mobile sim inside, and the it works, fin the signal-carrier.
    If you´re stock without wettin’ work it, tray ir, more if you already have the 6.15.00 baseband. good luck!

  • kaakutha

    no service still can anyone fixed …?

  • Abhinav4u Apple

    dude i cant find any carrier what to do??????

  • Taufiq Ridha

    For ALL OF YOU THAT CANT UNLOCK , PLEASE REJAILBREAK WITH REDSNOW 09.9b7 .CHECK INSTALL CYDIA + INSTALL IPAD BASEBAND. IT SHOULD BE WORK! 

  • Dungarchand

    Yes…
    Check ok for
    Install Cydia + Install IPAD Baseband
    while jailbreaking through Redsnow…

    Once done… In Cydia… Install Ultrasn0w

    This helped Unlock Sim !!!

    thanks Rbenitezz and Taufiq Ridha for the findings…

  • KKTan

    Why isnt there any answer? We’re a;; having the same problems but the SOAB person who made this info doesnt even bother to reply! Do you think it’s funny?! Not being able to use an iphone?! Dammit you guys

  • Vamshi1285

    I had also same problem unable to find network list plzzzzzzz help me

  • Cadasila

    Help!
    Perhaps I am asking an obvious question, but I am stuck. I did all of the above and it seemed to work perfectly. Then I took it to T-mobile to get a sim card and we couldn’t get a wifi signal no matter what we tried. Now I am home again and I do get one, and I didn’t reboot, or change anything. What’s wrong?
    Do I have to put a sim card in first? its a 3gs running 5.0., firmware 5.16.05. :-)
    Any ideas?

  • Cadasila

    Does the sim card already have to be in the phone before you jailbreak it?
    How exactly do you install IPAD baseband?
    Thanks for any help!

  • Ccrnpt

    Hi,, I did everything as instructed and my 3gs is with system 5, on 6.15.00 baseband but doesnot recognize my carrier chip.   please help !!

  • Romero1150

    This worked for me, just wait a long while for it to get signal. After placing the phone in plane mode and then off, wait for it to catch the signal repeat 2 or 3 times. Is it just me or do your phones boot fine untethered! 

  • Daniel

    there’s a special “trick” that iPhone3GS owners with baseband 06.15 need for iOS5. During the new setup screens you see when you start iOS5 for the first time, you’ll be asked about Location Services. Be sure to select “Disable Location Services” when asked! Later on in the setup, you’ll have the chance to turn on Location Services again when asked if you want to use “Find my iPhone”. It’s fine to turn it back on at that point, if that’s your desire (or you can always go in and enable it in Settings.app).

  • Toronomilash_ok

    I am looking to ultrasn0w is Cydia and it doesnt appear, I have already installed the repo666 source…

  • Alpha Fixer

    TO FIX THE NO SERVICE PROBLEM: open redsnow click Jailbreak and follow the steps THEN CLICK add cydia, Deactivate AND install ipad baseband. click next and let it RE-Jailbreak the phone and when it boots up your sim card will be fully working again.

  • annonkg

    What if my modem firmware is 05.16.05 its not listed as supported for ultrasnow?

  • Guest

    The same problem here:( 
    works with another sim-card, but for att  -no service

    thanks a lot. it’s working except that my 3GS couldn’t sync with itunes: it says “the sim card inserted in this iphone does not appear to be supported. is there a way to sync with itunes? thanking in advance for any help…

  • tuffknox

    during installing ultrasnow i get a message that reads “cannot activate cellular data network” and it doesn’t unlock my iphone…don’t know what else to do since i’ve exhausted every other means. i’ve rejailbreaked my phone installed baseband width 6.15.00 and still no unlock

  • Drimran12

    will it be possible to down regulate to 4.1 after selecting ipad baseband. 

  • David Callano

    Okay I had the problem where my sim card was not being recognized, I followed these steps for the 5.0.1 update to jailbreak and unlock. I happened to update it via apple (which I regret and should have used a custom firmware, never use stock for unlockers right?) and I jailbroke it with redsn0w 0.9.8b8, I have the 6.15 baseband (ipad baseband) and cydia. I tried to use ultrasn0w which didn’t work. I read some of the comments and someone said something about using a custom ipsw. Since I don’t run an apple computer, I downloaded snowbreeze and created my custom ios5 but it did not recognize the 5.0.1 firmware so I used the 5.0 firmware (I have an old bootrom for 3gs) and followed those instructions and installed it and it actually reverted it back to 5.0 ios! I then ran ultrasnow again in vola! I now have service! I was panicking that i wouldn’t be able to use it again…

    Hi
    I have iphone4 and updated to 5.0.1 using sn0wbreeze and was able to unlock with Gevey. Great
    Also have 3GS and also updated to 5.0.1 using sn0wbreeze but unable to unlock it with ultrasn0w 1.2.4. A lot of people are having this issue too.
    There are different suggestions out there, but none worked for me. I read this somewhere try this out may work for you:

    Note: there’s a special “trick” that iPhone3GS owners with baseband
    06.15 need for iOS5. During the new setup screens you see when you
    start iOS5 for the first time, you’ll be asked about Location Services.

    ok so i have iphone 3gs on ios 5.0.1 old BB 06.15.00 its already jailbroke and all that crap so whenever i download ultrasn0w its fine everything works except when i reboot after its all done downloading. Whenever i go to carrier/network list and turn off automatic it says this “unable to load network list ” and it also says no service on the status bar. ive tried restoring, ive tried sn0wbreeze to redsn0w ive tried everything in the book and yet everything is the same. ive also heard though that ultrasn0w is not supported with ios 5.0.1 but also have heard that it shouldnt matter as long as i have the old baseband (06.15.00).

    Wait a few minutes and working.

    Thanks manu you are a real star.  My daughter accidentally upgraded her jailbroken and unlocked iPhone to iOS 5 by mistake and it wiped out the unlock and we just got NO SERVICE. I have been trawling the internet and trying many many variations (very similar to yours below) but none of them worked. Yours has finally worked. Thank you.  I was very close to having to get a new phone before xmas.

    IOS 5 Baseband 6.15.00

  • Brookinscomm

    GK you are a genius.  One of the few people who actually knows what they’re talking about.  I’ve tried EVERYTHING to get this 3GS on 5.0.1 with 6.15.00BB to unlock.  Jailbreak, no problem. I was always suspicious when all the sites said, “use the 5.0 ipsw, it will work”.  I know there has to be some files that are different. But I don’t know what they are or how to change them.  I have 15-20 hours invested in getting this done.
    THANK YOU VERY MUCH
    You are a class act, dude.

  • Lauu Garcia

    IT’S THE SAME SITUATION!!! WHAT HAPPENED???

  • Ahari36

    everytime i install ultrasnow it has a ? before it and my phone does not unlock, what should I do

  • Lai

    You’re a genius, thanks!

  • BossT

    after you finished all the instructions up above, insert simcard, and go to options, and turn on airplane mode then wait till the airplane icon shows then turn it off. Wait a few minutes cause it will show you it is searching. There you go, your iphone is now unlocked.

  • simpleguy28

    I got an iphone 3GS baseband 5.15.04. Does anyone know if this can be unlocked by the new ultrasn0w?

  • Callum McKain

    okay, i have downloaded 5.0.1 from itunes as a mistake, I have tried so many things to try and get this to work. The iPhone was originally on o2-uk, and i have a 3 mobile sim which i want to work on it. 

    i have tried to jailbreak it and unlock it for the last 6 hours, however no matter what i do, i cannot get past the activation stage. I have tried to activate it on my 3 simcard, an old o2 simcard, wirelessly, and through itunes. None of these methods have worked for me. 

    I am using a macbook pro, and am near giving up hope, please can someone help me out on this, I want my iphone back! 

  • Anas Aoulad Rahmoun

    Super Thank You! I tried 10 ways In a hard two last nights.
    But finally your solution saved me.
    I suggest to every body to try what you said.

  • Jamie

    how can you tell if its unlocked besides the clear answer by trying a sim card, because i would prefer to know if i’ve done it right before i buy a new sim card, thanks

  • Shash

    Hi,

    Please help me in getting my phone unlocked. I have tried in many ways but last 4 days i am not able to use my phone. Below is the issue.
     
     
    I had iphone 3gs unlocked with 4.3.3, it was working well with no issues.
    Last Sunday i got an update in cydia in changes for mobile substrate, as usual i clicked ok to update it. but it went blank screen, and got stuck in apple logo.

    With no option i restored it in itunes to 5.0.1, without preserving my baseband using snowbreeze, and i have jailbroken it with redsnow 0.9.10b3.
    Now i have also installed ultrasnow 1.2.5 with wifi, as i dont have an option of using my cellular data.
    But still not unlocked, please help me how to get my phone unlocked, waiting for your reply.

    Now can i restore again with itunes with preserving with snowbreeze and jailbreak it again? will now my ultrasnow works?
     
    Thanks
    shash

  • Audrius25

    I did same mistake. My iPhone was fixed in shop, they said need to be downgrade to version 4.3.3 at least. 
    It was before Christmas, now maybe is new updates.

  • Mtawheed

    My iphone 3Gs is officially unlocked. I was running iOS 4.3.3 which was great, I decided to update to iOS 5.0.1. I connected to iTunes then checked for updates after the update had finished,  I started to activate my phone selected English, Egypt, Enable location services ticked, wi-fi selected then activating your phone appears. It may take upto 3 minutes to activate your iPhone appers. After the three mins have elapsed I get, your iPhone could not be activated because the activation server is down, pls try later all the time it is showing no service.
     
    The problem I was experiencing after I updated to iOS 5.0.1 is I cannot activate my phone and my sim card cannot be detected properly (no service), but my sim works fine when I use it in a different phone.
     
    I was stuck in this so I jailbroke the iphone and now it is activated but no sim card – no service all the time.
    When I go back to an earlier ios (4.3.3 or 4.1) I get the same issue (no sim card – no service)
     
    I don’t know what is wrong..
    My device details:
    iphone 3GS new boot rom
    ios (5.0.1 or 4.1 or 4.2.1 or 4.3.3)
    Baseband 06.1500

  • Mtawheed

    Is your iphone new or old boot rom ?

  • auctionista

    I left the phone in situ and it completed the the download. Everything works as it should now. Thanks.

  • roberto

    Que hiciste despues del error ??? me pasa lo mismo..

  • roberto

    What did you do after the error? I feel the same ..

  • auctionista

    Roberto,
    I left the iPhone plugged into the computer via USB because I was busy with something else. I didn’t let it sleep – when it dimmed I touched the screen to waken it. After 5 – 10 minutes the iPhone screen suddenly displayed the firmware being downloaded.
    Then I was able to follow instruction 6 and 7 (above).
    My iPhone works now and I hope yours will too.
    Good luck.

  • Chintu

  • Rui

    Hello how are you?

     I bought my iPhone 3GS in Canada some months ago, and unlock it there so I can use here in Portugal.
    After a while I upgraded and got the iPhone locked.
    I tried to find a way to unlock it and I got the new version 5.0.1 and the new firmware 06.15.00.
    My iphone was not working until I found this site with the following information:

    Iphone 3GS
    BB 06.15.00
    - Remove the phone’s SIM CARD
    - Make the update from itunes to 5.0.1
    - When the update is completed don’t do anything on the iphone.
    - Download redsn0w and iPhone2,1_5.0_9A334_Restore.ipsw
    - Open redsn0w > Extras > Select IPSW and then select the .ipsw file
    - I have an old version so i just click “No” > back
    - Click Jailbreak
    - Click Cydia
    - Click install IPAD Baseband
    - Click Deactivate
    _ Next and make the procedures of holding the buttons
    - Wait for the Jailbreak
    - When the iphone is back again put the SIM CARD again
    Wait a few minutes and working.

    I did this several times, and it only worked when I did that but excluding “Click install IPAD Baseband”and “Click Deactivate” and with the Iphone in AIRPLANE MODE.

    This week I connect the Iphone to Itunes and when I did Restore my Iphone blocked again.
    I tried to do the same procedure but it never works.

    Do you have any solution for me?
    My email is: rui_m_martins@sapo.pt

    Thanks

  • Humbertojurado

    Thanks, it worked… This helped Unlock Sim !!!

    I have an iphone 3gs jailbroken and unlocked using 6.15.00 ipad baseband.  I used redsn0w 0.9.9b6 to jailbreak.  I’m wondering if I can rejailbreak with a newer version of redsn0w because I have read that the newer versions have fixed the battery issue.  I’m having a lot of trouble with my battery.  I tried upgrading to 5.0.1 and I wasn’t able to do it, I think I was using the wrong IPSW files.  I don’t even need to upgrade to 5.0.1.  I would just like to fix my battery problem.  Thanks.
