How to Unlock an iPhone 3G using yellowsn0w

Alright folks, here’s the tutorial some of you have been waiting for on how to unlock your iPhone 3G! This is relatively a painless process but I’ll try to make it as simple as possible. Earlier we mentioned how yellowsn0w will unlock firmware 2.2 and the latest 02.28.00 baseband!

How to Unlock your iPhone 3G using the iPhone Dev Team’s Unlock, yellowsn0w

If your iPhone 3G is already jailbroken, jump to step 3 (you already knew that):

1. Update your iPhone 3G to 2.2 firmware via iTunes (to ensure you’ll be on baseband 02.28.00).
2. Jailbreak using QuickPwn 2.2 (updated with 2.2 download links).
3. Launch Cydia –> click on Manage –> click on Sources –> click Edit –> click Add –> enter the following Cydia repository URL found here –> Click on Return to Cydia.
4. Click on Search. Type in “yellowsn0w”. Install yellowsn0w (it should be version 0.9.1, it was updated fairly quickly). Let it finish installing, exit Cydia.
5. Reboot your iPhone with foreign SIM installed…10 seconds later after reboot you should get a signal. If you don’t, try taking the SIM tray out then reinserting again.
6. That’s it! Your iPhone 3G is unlocked!

I installed yellowsn0w was able to pop in my du SIM card I was using in Dubai on my iPhone 2G. At first I quickly saw the “SIM Failure” message pop up then disappear quickly. The du SIM was able to pick up a signal! Success!

If you had success or some problems, let us know, but more important, let the Dev Team know by posting comments on their blog here. It’s imperative for them to get feedback in order to improve yellowsn0w to work for all carriers from around the world!

Big props to the entire iPhone Dev Team for their hard work. The entire globe is thanking them right about now!

    Hey all,

    I have successfully unlocked a Fido iPhone 3G.
    I can get the phone to use the Rogers SIM, but there are still some bugs with the yellowsn0w app.
    I can receive calls however I am unable to make calls from the iPhone. When I try to do so, it loses the signal and unregisters the SIM. Eventually it re-registers the SIM and again I am left to where I started.

    I have let the Dev Team know about this bug. If someone has something else to share, please do so here!

    Happy new year!

    Why not, with quickpwn its so easy, and if you’re worried about warranty just make sure to restore your phone before you bring it in.

    I updated to the newest 2.2 and ran quickpwn 2.2. After i finish running quickpwn, it shows that it was successful, but Cydia does not come up. I have rebooted several times, and no change. If I restore, what will it restore to? I had a jailbroken phone before, so will it restore to that point, or to a otb iphone? Anybody else have this problem??

    Successfully jailbroke my iPhone 3g (Version 2.2 and Modem Firmware 02.28.00) that I bought in the U.K. locked to O2 carrier and installed yellowsn0w 0.91 using Cydia but no luck when I changed my O2 SIM for my Rogers SIM. Just got an error “Invalid SIM” – no signal strength or carriers name. I’ve tried the usual tricks e.g. Airplane mode, rebooting, resetting Network etc that the forums are suggesting.

    I guess I’ll uninstall yellowsn0w, and continue using my O2 SIM with its expensive roaming charges and wait for a fix from the MuscleNerd and his friends. However I’d like to thank the team for the work they’ve done so far, obviously some people have got the unlock to work. Carry on the good work – “if at first you don’t succeed, …”

    Worked for me in 2.5G GSM network. Done the following steps.

    1. Restore to 2.2 in itunes (without SIM).
    2. jailbreak by QuickPwn 2.2 to add Cydia and Installer (without SIM).
    3. installed Terminal and SBSettings without upgrading Cydia (without SIM by wifi).
    4. installed yellowsn0w 0.9.4 from cydia adding source http://apt9.yellowsn0w.com
    5. insert 3rd party SIM and rebooted from SBSettings.
    6. find 5 dots and no carrier logo for several mins after rebooted. (got null/null in carrier)
    7. went to terminal and type following commands
    a) yellowsn0w -c
    b) yellowsn0w -l (done it several times, when it works it takes longer like 1 min. and got null/2.9 in carrier & ICCID loaded)
    8. rebooted again from SBSettings.
    9. after reboot find the phone searching for network and it got signal at last. both carrier and ICCID loaded. now carrier shows Carrier/2.9.

    After that voice call (both MO/MT), SMS & Edge working fine. Got no 3G service yet so will check 3G later. Hope 3G will also work. Unlock is ok and also works after reboot.

    Main parameters to check in the about screen Carrier & ICCID. if both loaded perfectly then it should work. if not loaded then re-install yellowsn0w from Cydia or Installer and try those terminal commands until those parameters are loaded.

    Great job done Dev-Team. And best of luck to the users.

    9. after reboot find the phone searching for network and it got signal at last. both carrier and ICCID loaded. now carrier shows Carrier/2.9.

    After that voice call (both MO/MT), SMS & Edge working fine. Got no 3G service yet so will check 3G later. Hope 3G will also work. Unlock is ok and also works after reboot.

    Main parameters to check in the about screen Carrier & ICCID. if both loaded perfectly then it should work. if not loaded then re-install yellowsn0w from Cydia or Installer and try those terminal commands until those parameters are loaded.

    Great job done Dev-Team. And best of luck to the users.

    Hello fellow Canadians,

    Success! with Yellosn0w 0.9.5 for me.
    Unlocked a fido locked iphone 3G and used a Rogers SIM to make and receive calls.

    Steps used:
    1) Remove yellowsn0w 0.9.4
    2) Restart using Bossprefs
    3) Installed 0.9.5 kept SIM in the phone.
    4) Reset Network settings which automatically rebooted the phone.
    5) Waited a bit to open Home screen, after which I saw that it was connected to Rogers.

    Hope this helps!

    Thanks Dev-Team.

    Iphone 3G locked to Rido, jailbroken, unlocked with yellowsn0w 0.9.5. with 0.9.4, I used to be able to get signal, but outgoing calls would result in dropped signal from Rogers. After updating to 0.9.5, the phone gives me an “Invalid Sim” error and never connects. Tied resetting network settings, and enabled/disabled airplane mode…same result

    And ideas?

    I would try doing a clean restore to 2.2 firmware, then running QuickPwn 2.2. Make sure you download 2.2 firmware and put it in a folder on your desktop.

    Plug in your iPhone and launch iTunes. Sync so everything will be backed up, then click “Restore”. This will reset your iPhone to factory settings so it will be like a brand new iPhone.

    Next, download QuickPwn 2.2 along with the 2.2 iPhone 3G firmware. Links can be found on my post “How to Jailbreak your iPhone 3G with QuickPwn.” (one of the popular posts along the sidebar).

    Launch QuickPwn and follow the steps. You should be fine.

    Having problems unlocking my friend phone. He gave me 3G phone and I don’t know if it was previously hacked but I used pwnage 2.2.5 and firmware iPhone1,2_2.2_5G77_Restore.ipsw. It created the custom ipsw and then I restored this with itunes. I then tried yellowsn0w by installing it with Cydia and I still could not see a network. I thought it was down to the fact that I had put in a non 3-g sim. But I put my own 3G sim in the phonen and still can’t see the network. So I then restored again to the 2.2 firmware through iTunes. I then used Pwnage to install iPhone1,2_2.2.1_5H11_Restore.ipsw. It again created the custom restore so I restored this again through iTunes. Installed yellowsn0w again but I still can’t see a network????? The baseband is still at 02 28 00.

    Any idea’s how I can get the service provider.

    Carrier doesn’t how up in settings. I just get ….. at the signal bar on the top left.

    Anyone have issues with this. I am able to jail break the phone and run yellowsn0w 0.9.8 but if it locks up or if i restart or shut the phone down. when i get back in the phone doesn’t work, so i have to reinstall with a sim that comes with the phone and then stick the fido card in, and it is ok. basically anytime i have to shut or restart the phone it seems to be locked again. I have a rogers iphone 16gb, 3g, brand new, with fido sim. Just kind of a pain to do it all over if I restart. I have run into situations where the phone was out of battery, so I have no choice.
