UltraSn0w: Software method to Unlock iPhone 3G running iPhone OS 3.0 Released

The iPhone Dev Team has released their much awaited software method called Ultrasn0w to unlock iPhone 3G running iPhone OS 3.0.

It's also makes it the world's first software solution to unlock iPhone 3G running iPhone OS 3.0.

The iPhone Dev Team had released their PwnageTool 3.0 for Mac on June 19 to jailbreak iPhone 3G running iPhone OS 3.0 and then followed it up by releasing Redsn0w for both Mac and Windows users on June 20 to jailbreak iPhone 3G running iPhone OS 3.0.

PwnageTool and Redsn0w can also be used to unlock iPhone 2G.

They have just released their much awaited software method called Ultrasn0w to unlock iPhone 3G running iPhone OS 3.0 which can be installed via Cydia or Icy.

Dev Team has published the following instructions:

  1. Ensure you have upgraded to iPhone OS 3.0.
  2. Jailbreak your iPhone 3G using redsn0w or PwnageTool (this will also install Cydia/Icy).
  3. Run Cydia or Icy.
  4. Please add the repo repo666.ultrasn0w.com to Cydia or Icy.  That last “o” is actually the number zero “0”! If you use the letter “o” you’ll get an error.
  5. Search for ‘ultrasn0w’ in cydia or icy and install ultrasn0w.
  6. Reboot your iPhone 3G.
  7. T-Mobile USA users should disable 3G before using ultrasn0w.

Please note that UltraSn0w currently does not unlock Apple's new iPhone 3GS.

But please proceed with caution and don't forget to tell us if you were able to successfully unlock your iPhone 3G.

Thanks everyone for the heads up!

    The easiest thing i've ever done. Worked without a problem.

  • dustin hunt

    i successfully downloaded and unlocked my iphone 3g 16gb using ultrasnow on the t-mobile network.

  • dustin hunt

    like gm0n3y44 said, easiest alteration i have ever done to my iphone.

  • cristv77

    works perfectly in costa rica "I.C.E" network, i had a small problem but nothing that redo all over again cant fix, it was a great job by Dev-Team, thanks and much respect @ them

  • ffs – i thought ultrasnow was supposed to fix this little 3G S problem…

    I guess I'll wait another week….




  • gatz

    arghh im so jelouss u lot all hav it workingg except me with the no serviceee

  • Iphoneninja

    It's was ment for the new firmware not the new iPhone.
    But the 3GS uses the same baseband that's being exploited in ultrasn0w.
    Better buy it now before apple "fixes" it!!
    Mad props goes out to the dev team hope it comes out soon
    I miss themes and sb settings and insomniac user agent faker aaahhhhhhh!

  • Buy what exactly? I already have the 3G S…

  • Greg

    Can anyone tell me the step by step procedures to upgrade a 3g that is running 2.2 and is jailbroken and unlocked. Do I use iTunes to Update or do I use Restore? I don't want to screw it up. I know to use redsn0w, then run Cydia and ultimately ultrasn0w. Thanks!

  • s

    Restore to 3.0 from itunes, download redsnow and run, add ultrasnow source to cydia, follow instructions. http://blog.iphone-dev.org/

  • Andre

    Working here on O2-UK iPhone with Orange UK sim card.
    Nice one Dev-Team.

    iphoneunlockuk is a ********. Well you know what I mean.

  • ZedSefi

    Second that 😀

    but I wonder why can't we use ultrasn0w to unlock iPhone 3GS as well since it is running on the same baseband?!!!!

  • Rafa

    how do you add the repo repo666.ultrasn0w.com to Cydia????

  • ZedSefi

    Please try again, also check your SIM card. Today I had the same 'no service' issue when I put my old pay&go SIM card in my iPhone 3G after unlocking it with ultrasn0w. I became very nervious and thaught that I lost unlocking chance maybe forever, but then I swapped my SIM card with somebody else in the house to check it out. Appeared to be that my SIM card did not work on my friend's Nokia phone while his SIM card worked on my iPhone (it is from Vodaphone UK). So it must be that my SIM card has been expired and became non active after leaving it for so many months without using it. I was pretty sure it is ultrasn0w's fault but now I know that it is not. ultrasn0w WORKS, it's just my SIM card is dead.

  • DigiBloke

    Excellent work guys…
    Let it sn0w, let it sn0w, let it sn000000w…!!!

  • cristv77

    wow, his still doing the same again?, this is old story, i cant believe that he still fooling some ppl around: take a look at this from 5 month ago: http://blog.iphone-dev.org/page/8

  • Frank

    can the iphone be cracked for use on Sprint someone asked i am not 100% sure

  • Mikeyxx

    Go to manage, then add repository (I think, I don't have my phone jailbroken right now, so I can't recall)

  • Ronnie

    Tried it worked great, but I tried sending a text message to the iphone with tmobile sim and messages aren't received. Any ideas?

    Thanks for the great work Dev Team!

  • Don

    It works great thanks dev team but I got problem updating my cydia installer it giving an error message after downloading the file.Why is it happening?

  • cristv77

    do have to go manage in cydia, but after go to source, and ad, a new sourceL repo666.ultrasn0w.com, and thats it

  • Colon Powell

    I heard that if you unlock your iphone with ultrasnow hot women will randomly walk up to you and give you a blowjob. Has anyone else heard this?

  • Dacha87bgd

    Because its the question if 3gs can be jailbroken, if it can the same injection vector can be used to inject ultrasn0w into baseband, i hope someone can figure it out before apple close that hole in 3.0.1 fw probably soon!!

  • Thanks for Ultrasn0w, I've been looking forward to it and it does in fact unlock the iPhone. That said I am receiving the message 'Could not activate cellular data network: You are not subscribed to a ceullar data service', when in fact I do have a data plan.

  • GlobeTrotter

    I can confirm that I have been getting getting blowjobs from random hot women since I've unlock my iphone 3G with ultrasn0w.

  • Simo

    I also confirm that the redsn0w, then ultrasn0w combination has successfully unlocked my 3G, for use with Vodafone UK, on OS 3.0

    Although I've read a few issues with the procedure over the net, I followed the step by step guides and it worked perfectly.

    I also had the "Could not activate cellular data network:" messages at first, but due to the APN settings being reset to incorrect values. I altered these and it works fine.

    Also have MMS setup for Vodafone UK now too. If anyone needs the details… fill in the fields, then reboot and add your phone number in general settings: –

    APN: wap.vodafone.co.uk
    Username: wap
    Password: wap
    MMSC: http://mms.vodafone.co.uk/servlets/mms/
    MMS Proxy:
    MMS Max Message Size: (blank)
    MMS UA Prof URL: (blank)

  • Irha

    Is there anything to watch out while upgrading an iphone 2G from a very old firmware (1.4)? Should the baseband be preserved or can we let iTunes upgrade everything to the latest?

  • Back up everything and go for it

  • Underwater Mike

    Nope. Sprint is CDMA.

  • Just had a question about certain programs not working after the jailbreak. I did a jailbreak with an earlier version of dev teams hack and found that after I lost my Google maps where before I could use the subway and bus time schedules on my Google map and after the hack it was gone. Also I had problems with regular programs not wanting to work from the app store, kept saying please upgrade to 2.2 and so on. The question is if I Jailbreak my 3.0 3G will the same happen again or maybe I didn't jailbreak it properly in the first place.

  • it's working!!

  • gabe

    Do you know where I can find the MMS info for T-Mobile USA?

  • I've unlocked 12 iPhone 3G's with no problem (all running 3.0) using Ultrasn0w….

    I love the dev team…

  • Andre

    Here's how.

    That's all there is to it, Cydia will download the required files then just search for UltraSn0w.

  • Settings-General-Network-Cellular Data Network and enter wap.voicestream.com in the APN under Cellular Data (that's for T-Mob USA). That's it, back out and your data should work. It worked for me at least.

    On a side note I appologize for the n00b question, but I guess if we are using T-Mobile we can only connect to Edge?

  • bj man

    I got 4 blow jobs and a rim job since I unlocked mine 20 hours ago

  • Matt

    I have AT&T right now on my iPhone 3G 3.0. If I unlock my iPhone which cellular networks would I be able to use? Just t-mobile??

    iphone 3G 2.1 running with yellowSn0w, i also have windows, no mac, do I have to install redSn0w and then ultraSn0w after upgrading to 3.0 or I just upgrade to 3.0, run cydia and install ultraSn0w? Sorry for the question but I am missing something here I guess. Thanks dev team rocks!!!

    This is error message that I got while updating my cydia installer.

    Error: Couldn't configure pre-depend dpkg for ncurses.probably a dependency cycle

    Any solutions?

  • My jailbreak and unlock worked beautifully (thanx a million) but my internet with my tmobile sim card isnt working. It says I'm not subscribed to a cellular data service but i am (or at least I pay for it every month). Im unsure of what to say to customer service under the circumstances…is there a certain type of internet i should be subscribed to? Thank you in advance if anyone can help

  • Rich

    I'm trying to run redsnow on my iphone 2g. Everything starts out fine, but after "2nd stage" it says "waiting for reboot" and the reboot never happens. Anyone had that happen? Suggestions? It may have something to do with this phone is not active, i'm using my old sim card. Does that matter?
    Thanks for the advice.

  • Rich

    After running redsnow on my iphone 3G I've tried to re-install apps I had on the phone before I updated to 3G. Intelescreen (lets you view calander on lock screen) locks up the phone due to the "rock extensions" so I've had to delete that. Also, dreamweaver video recorder won't load. Anyone else having that problem? Are we just waiting for updates for those programs? Or is my phone just not working right. Thanks.

  • Don

    I'm found the solution from this site 'http://www.touchpodium.com'. When jailbreaking don't install icy,if you did just re-jailbreak it & it will fix the cydia installer update issue.

  • Dacha87bgd

    Sim card isn't a problem, did you restored it to 3.0 or updated? restore it to 3.0 and run redsn0w, that waiting for reboot thing could take up to minute as i remember, are you sure you entered the DFU mod correctly?
    Give us some more info and we will probably work this out xD

  • Kenny


    I have been using the 3G phone well until recently when I accidentally updated onto 02.30.03 base with 2.2.1 5H11.

    I then applied yellowsn0w, it reinstalled Cydia and all. But it didn't recognize the T-mobile SIM.

    Now I installed ultrasn0w (didn't apply redsn0w as they said not to do it for this baseband). I still cannot use my T-Mobile SIM. One mistake that I did while installing ultrasn0w was that I didn't switch off 3G initially. I reinstalled ultrasn0w; but the SIM still doesn't work.

    Can anyone help please!!!

    Thanks, Kenny

  • rich

    I have restored the phone to 3.0, and ran redsnow. I have an innactive sim in the phone right now. This is a first generation iphone. I've rebooted my computer and tried several times to run redsnow, but everytime I get to the "waiting for reboot" after the "uploading second stage", and the computer just says "waiting for reboot" every time. I've waiting for several hours, it's just not going any further. When I run redsnow I push the buttons at the appropriate times, and when it asks for the most current IPSW I have found the subdirectory with it in it and selected the most recent one. (same date as date I downloaded 3.0) I used this same format to jailbreak my other 3G phone and worked great.
    Thanks for your help.

  • Andres

    I can't jailbreak my Iphone 3g for some reason windows tells me that redsnow has encouter a problem and it shutsdown every time. Can anyone offer some advice please I already tried at least 5 times and nothing.

  • bob cu

    same thing happened to me when i tried running on windows 7. Try another computer or download redsn0w v0.7.2 from http://www.iphone-hacks.com/iphone-downloads/file/197

    good luck

  • bob cu

    upgrade to OS 3.0, then it shouldn't be a problem. I jailbroke and unlocked multiple 2G and 3G iphones. All worked well, so give it a shot!
    Good luck

  • Jaco

    new to jailbreaking

    I've unlock my 3G iphone and it worked great. The only problem is the 3.0 version now drains my battery. Does anyone have the same problem? Any way to fix that problem? Thanks

  • Mohammad

    It works quite easy and fast.

  • Kenny

    Hi Bob,

    Do I need to upgrade it thru iTunes (it is then saying to restore to factory settings – loss of media and other data, etc..) or is there any other way?

    I want to be sure before I take another step.

    Thanks, Kenny

  • Orlando

    And did 3G worked? My Friend Unlock and Jailbreakin a iphone 3g and when i put my tmobile(USA) sim card it only pick up E (Edge) not 3G. Did 3G worked for you?

  • See my comments above, you need to update your APN settings.

  • MeD

    Where do I go to download this program so that I can unlock/jailbreak my phone? Any info would be greatly appreciated.

  • Irha

    Thanks. Since it was jailbroken, I had a lot of 3rd party application data on it. Assuming I am going to reinstall at least some of them after jailbreaking 3.0, how do I backup and restore that data?

  • Amin

    It works perfectly, i tried it with my iphone and no error. Thanks Dev Team, keep up the good work. nobody does it better

  • TimW

    T Mobile
    UK01 (kiosks– spectrum interactive)
    Tesco (uses O2)
    Asda (voda)

    all the above sim tested and working.
    UK01 capable of 7.1 mbs not publicly available.

  • sry to bother you! i updated the APN & for some reason its still not working. I was on the phone w tmobile for an hour & still no luck. I didnt tell them i was on an unlocked iphone. It stopped working before the update. Do you know if there's a certain plan i should be on or is there a certain phone i should tell them i have? thanx

  • boo hoo

    love all the work Dev Team 🙂

    but I'm having a bit of a problem with Apple's software.

    I upgraded to iTunes 8.2, did a backup of the iPhone, and started a 'restore' to 3.0.

    Got an 'unknown error 1604', have tried again and a again but can't get any further. only thing different is I am now seeing an 'unknown error 1603'!! eek!

    I followed all of apples advice on their KB, anybody out there got any advice? all help greatly appreciated 🙂

  • I have a G1 Data Plan, so I don't think it matters. Do you have 3G turned on or off? Which APN did you add the wap.voicestream.com to? There are two listed on the Cellular Data screen, you only want to update the one at the very top.

    And my appologies update the following on the same screen (towards the bottom):
    MMS Proxy:

    Hopefully that works for ya.

  • muthu

    Thanks for this unlocking methods.I saw one sitehttp://www.mobileunlocksolutions.com/.In that site contains the unlocking codes and instructions for mobiles.Anyway this software method is very useful to me.Thank U

  • Armanius

    if your iphone is password protected make sure to turn it off.

  • Armanius

    if you want to jailbreak your iPhone(which you have to do first so you will be able to unlock it) you have to use redsn0w and after you done jailbreaking your iPhone you have to add this repo repo666.ultrasn0w.com to your Cydia and install Ultrasn0w

  • Don

    Select 'Manage' then go to 'Sources' then select 'Edit' and then select 'add' once key in select 'add source'

  • cmadiam

    followed all instructions but it doesn't work for me. I have 3G and updated to 3.0 and also jail breaked it before install ultrasnow but now, when i tried to reboot my iphone, only the apple logo appears…

    Can someone help me on this one?

  • Petre Cristescu

    I followed all the instruction and all works fine now.

    To be able to get good and permanent carrier coverage, I had to restore network settings after install ultrasn0w.

    Thanks for all you have done.

  • Erik


    I have the problem with "No service" after Ultrasn0w is installed.
    Followed every guide 100% and everything goes all the way just fine.
    But after i installed Ultrasn0w and rebooted. Searching, searching and then
    No Service ! 🙁
    Tried everything. Started all over 10 times, same result.
    What to to ?
    Anybody know of this problem.

    Thx guys.

  • pepenivel

    Vodafone Spain, iphone 3.0 jailbraked and unlocked following Dev Team´s instructions, working beautifully, THANKS A LOT DEV TEAM!!!! you guys are awesome!!

    Note about something I was doubting: If you have your iphone 2.1 or 2.2 with yellowSn0w you have to update your phone to 3.0 first, then jaibreak it with redSn0w which will install Cydia or Icy in your iphone, then get ultraSn0w thru Cydia or Icy.

  • dsfsdi

    AT&Ts 3G doesn't work on T-Mobil it's a whole different carrier -_-

  • I wish. The jailbrake worked fine. But the unlock keeps getting an error message when attempts are made from Cydia:

    How was it that my Cydia wasn't the latest version when installed?

    I have an iphone 3G running 2.2 (jailbroken and unlocked) what is the exact procedure to upgrade my iphone to OS 3.0 without losing the jailbreak and unlock?

    I am using Windows platform


  • Marcell M.

    Does jailbreaking my iPhone 3G with 3.0 with redsn0w restore it or does it do it as an update process? I hate going through restores and restoring from backups and installing apps again.

    Does redsn0w jailbreak by updating it or restoring?

  • Armanius

    has anyone tried with T-Mobile in US??

  • Mervin

    ok can we jailbreak the iphone 3GS yet????

  • darren

    huge thanks dev team for the speedy unlock for OS 3.0.

    piece of cake, upgraded my iphone to OS 3.0 via itunes then ran PwnageTool 3 to jailbreak my phone piece of cake.
    (however itunes didn't work and would not allow me to connect the phone in recovery mode until i had it connected to the internet).
    added the ultrasn0W as described (had an error at first so manually ran it) and hey presto iphone 3G 16GB v3.0 on UK orange network on holiday in ARUBA.

    took awhile due to firstly dropping my 2G iphone down the toilet, Breaking the display on my 2nd iphone 3G so had to purchase an new iphone 3GS and now dropping and breaking my new macbook pro 17". they say things come in 3 so lets hope thats it 🙂


  • Pinnu

    I am having iphone 3g firmware 2.1 , and i m not haivng lot experience in jailbreaking and unlocking but i have tried one time and was successful.I wanna ask that after jailbreaking my phone to 3.0 OS will my phone work fine but i will not be able to make calls and send messages? Will unlocking my phone will make phone able to make calls and will it work with all service carriers because i m using turbo sim?

  • JG

    worked brilliantly – thanks Dev team!

  • boo hoo

    Thanks, Armanius.

    it was password protected (time delay of 1 hour on the lock). but i didnt turn it off. now i can't turn it off as i can't access the phone 🙁

  • Kwopau

    I find that this is true with Vista. I also have Vista Home Premium and every time i tried, the program would close by itself and crash. I did jb my iphone 3G 3.0 using my other laptop which is XP Media Center Edition and it has worked. I suppose that some vista's doesn't work while some does?

  • Kwopau

    Well to be honest. Not all country allows it or has a specific code that needs to be used. I've had the same issue as you have, where I have it unlocked but it doesn't work with my service here in Korea. I do have a Korean Cell phone that has a SIM card and have the same issue. I believe it's still a hardware issue even though it is unlocked.

  • Kwopau

    this has happened to me a few times when I was using Vista. I was about to give up but i had a chance to use XP machine to jb my iphone 3G.

    If you have Vista, it may not work properly.

  • I've jailbroken & unlocked my 3g & everything is working as normal except cydia crashes on the loading data screen. Would anyone happen to know why this happens and how I can fix it? thank you

  • Kwopau

    you go under Manage and i believe the button is on the top left?

  • Kwopau

    Just connect your iphone to itunes and it will automatically back up if you have set it to do it that way. if not right click on your iphone icon on the left and select "back up now" and it should back up.

  • Kwopau

    Well any cellular networks that uses GSM would do.

  • Kwopau

    No. you must update to 3.0 and then install ultrasn0w.

  • Kwopau

    i would just update your iphone to 3.0 without preserving the baseband because ultrasn0w does work with the baseband that comes with 3.0

  • Kwopau

    in Windows did you hit the shift key? while holding the shift key click restore.

  • Kwopau

    If I were you, i would just back up the iphone and do a clean install of 3.0 then jb it and install ultrasn0w.

  • Kwopau

    once you unlocked your iphone 3G, you don't need a turbo sim anymore, so that you can throw away or give it to someone else. or do whatever you like with the turbo sim.

    when you unlock your iphone you can use anywhere that lets you use it. Some countries like South Korea have blocked people using their unlocked iphone 3G into their service.

  • niloy

    hi all
    I used ultrasn0w but after reboot it says 'waiting for activation,this may take some time' but one day already gone.

  • reibu@mac.com

    Hi guys

    we cannot download ultrasn0w via Cydia because the iPhone does not connect to our wireless network.

    F purple snow. Ultra snow is the shlttttttt!!!!!!!!! Too easy… F 3g net work 4g coming out…. Soon l. 3g will B 2 slow. Att will not hang with Comcast or clear or sprint.. From Corp monoply insider. Trust me

  • I have a dumb question. I ran ultrasnOw and it seemed to successfully install and I went through the reboot process and it started up ok.

    How do I know if my iPhone 3G is unlocked now?

    Let me explain. I live in Japan and my iPhone 3G is a standard issue Softbank (the carrier here) iPhone, that was locked to Softbank.

    My purpose in unlocking it is so I can use it on a trip to the U.S. next month. So my goal is not to avoid AT&T but to *use* AT&T. 🙂

    I would like to get a no-commitment contract from AT&T for when I am there.

    is there something I can check now on my iPhone to confirm that it is unlocked?

    What does the unlocking actually do? What is changed in the phone? If I "unjailbreak" my phone and restore to the original firmware will it be locked to Softbank again?



  • Hi there, I have the Iphone 3G 8gb, Ver. 2.2.1(5H11) and modem firmware 02.28.00, the last jailbreak I've done it is messing me a lot, my Iphone gives some errors when I connect to Itunes, doesn't install my App (even telling me that it is installed) and sometimes crashes (just reboot alone). I saw the release of Ultrasn0w and can't understand how to upgrade to 3.0 while apple store release the 3.0.1 (I think this is to prevent some people to unlock). I'm not going to upgrade to 3.0.1. I don't care to get or not the last unlock, I just want to see my Iphone working good with my different SIM (that is why I unlock the mobile) thnks ur attention, hugs

  • Yes the ultrasn0w works in version 3.0 however roaming doesn't work so i have to bring my spare erricson for my simcard roaming to work. Not like the yellowsn0w the roaming works fine and not need to bring spare phone just to utilize my simcard. Any help to fix the roaming issues.
