  • [ RELEASE ] 3G iPhone Unlocked - Eat the yellowsn0w


    You've waited. You've watched. You've waited more. Now... its here!

    The Dev Team has released yellowsn0w, the 3G iPhone unlock. Its available NOW via Cydia, you'll need to add their source (check the release post for the URL - they'd prefer sites didn't link the repo url) then check your Changes tab - yellowsn0w should be right on top. If you don't know how, here's how to add a source in Cydia. Refresh if you don't see it. If you're reading this later, just search for yellowsn0w in Cydia (making sure of course you've added their source). As guessed (and confirmed a bit later) from their post earlier today, IT WORKS WITH THE 02.28.00 BASEBAND version - in fact, ONLY for that baseband version. Meaning yes, you will need to update in iTunes and then use PwnageTool on a freshly updated 2.2 iPhone if you DON'T have 02.28.00 right now. Running the unlock on older basebands will simply cause it to exit, and do nothing. "No harm, no foul."

    All you do is go to the package in Cydia and install just like you'd install any other package. Boom - restart the iPhone, and...

    ...wait for the slide to unlock screen, then wait 10 or 15 secs more. If you don’t see your carrier name pop up, then remove your SIM, reinsert it, and wait 10 secs more. This is the step we’ll be working on eliminating next.
    Then you're unlocked. A quick note for users whose SIM cards come preinstalled with menus or apps on them, you'll

    ...need to pull and reinsert the SIM once after rebooting the phone to engage the unlock. Even though it’s needed only once per boot, it’s still a nuisance and we’ll be fixing that ASAP... You’ll know if you fall into that “extra step” category if your carrier doesn’t show up within about 10 seconds of the slide to unlock screen.

    There is a known issue with SIM cards that have STK (SIM Toolkit) application menus, these menus are usually items such as “top up” “get credit” etc. These menu items confuse the application sometimes, removing and reinserting the SIM fixes this issue.
    Answers to some potential questions:

    My modem software says I have {less than 02.28.00} - can I still unlock?
    Yes, but you have to upgrade your baseband to 02.28.00 before you do anything. First restore completely to 2.2 in iTunes (just connect the iPhone to the computer, go to the iPhone tab in iTunes, and press Restore in the version area).You can follow this guide to jailbreak after, then install the unlock from Cydia.

    Is this permanent? In other words, will I be able to upgrade my firmware when the next one comes out and keep my unlock?
    No. This is a soft[ware] unlock, not a hardware unlock, so you'll need to do as we've mostly been doing - wait to upgrade on new firmwares (all current firmwares are unlockable as of now) until the Dev Team releases a patch. Of course we'll have details for you every time Apple comes out with a firmware update.

    What if I WANT to remove the unlock?
    yellowsn0w is completely removable through Cydia, the command line, and iTunes.

    I'm still on [2.1 / 2.0.2 / 2.0.1 / 2.0] firmware on my iPhone 3G, but would like to upgrade... what should I do?
    Back up your iPhone. Restore in iTunes. Follow this guide to upgrade to 2.2 jailbroken, then simply install yellowsn0w from Cydia when you're finished - unlocked, jailbroken, enjoy.

    I have T-Mobile, and they've recently upgraded their network to include 3G. Can I use the T-Mobile 3G data network with my unlocked iPhone 3G?
    No - T-Mobile and AT&T use different 3G frequencies, so your iPhone 3G won't pick up T-Mobiles 3G network. You CAN however still use T-Mobile EDGE and GPRS just fine with the iPhone 3G - as well as all T-Mobile's voice features, and WiFi of course.

    I have AT&T. I don't plan on selling my iPhone anytime soon, and I'm staying with AT&T. Is there any benefit for me to unlock my iPhone?
    Nope. Aside from the ability to use the iPhone 3G on other networks than it comes locked to (T-mobile in the States, various carriers elsewhere), and the higher potential asking price if you sell your iPhone unlocked, there are no benefits to unlocking your iPhone.

    OMG WTF BBQ!!!! This is awesome and I want to donate. Who do I send money to?
    Don't. They like uh... post cards. Scanned. And emailed.

    I think you're wrong about the basebands it will work with. I have an older baseband, and I'm going to run the unlock anyway. I think it will magically work in my case.
    I'm going to have a sandwich. After we each do these things, lets reconvene and see who's happier.


    [B]Edit: T-Mobile USA Users must turn off the 3G toggle in settings.

    Everyone: You MUST have your SIM card in (without the proxy chip) throughout the entire process. With your SIM card installed... Install yellowsn0w 0.9, then reboot and wait up to 2 minutes for the phone to get service. If it doesn't work then uninstall 0.9 and try version 0.91. Keep reporting

    If you have a SIM PIN you will need to REMOVE this first before running yellowsn0w... it is not compatible (yet)[/B


    Update: Version 0.9.5 should fix T-Mobile USA outgoing call SIM issues.

    EDIT: In case there is still any confusion about how to unlock your 3G iPhone, a tutorial has been created. Be sure to read the instructions very carefully so that you are on the right firmware or you maybe never be able to unlock your 3G.

      heres everything that i did

      1)update to 2.2 via itunes
      2)use quickpwn 2.2 to jailbreak and activate install cydia and installer
      3)install yellowsn0w and sbsettings via Cydia (intalled 0.9.4 at the time)
      4)reset network settings and reboot with sbsettings
      5)waited for the phone to say "no service" (sometimes it took a while)
      6)then toggled airplane mode on for a few seconds then off (started searching and came up t-mobile) only outgoing calls didnt work
      7)woke up this morning only to find another update 0.9.5 WAHOO!
      8)updated via Cydia
      9)reset network settings and reboot with sbsettings
      10)waited for "no service" then toggled airplane once more then BAM fully unlocked iPhone 3G 8GB Black on T-Mobile USA


      oh yeah after your phone is working you might want to turn on my caller ID, otherwise you will come up as "unknown" , you can find it under settings/phone menu

      if you cant get service at all, removing and reinstalling yellowsn0w then reset network setting and rebooting with sbsettings helps. also removing the sim card never EVER worked for me. i think its an unecessary step.

      it should now say "searching" at the top left
      now it should read your carrier

      it worked perfectly for me
      That didn't work for me at all. I must have did that a hundred times. I finally reset all settings and it worked out for me on 9.4 but I think 9.5 fixed all the issues. I would suggest to still reset all settings if I had problems with 9.5

      UPDATE
      T-Mobile US here with a newer SIMM

      At first, using the initial Yellowsn0w release, I would see T-Mobile bars but couldn't make calls, after updating to the last Yellowsn0w relaese, I could no longer connect to T-Moible.

      Today I followed these instructions listed here
      Hack that Phone - Unlocking the 3G iPhone with QuickPwn

      Note there are 2 pages, I used every single step including SSH.

      Finally I rebooted my phone, turned off Airplane Mode, then back ON, the phone searched for the Network, then Boom T-Mobile was found.
      Now I'm able to receive and make calls , the only thing I noticed, every time I reboot my phone, I have to do the Airplane Mode thingy.

      By the way, I have 3G and data roaming enabled as well.

      2.2 Restore Firmware from modmyi wiki
      quickpwn 2.2 (Jailbreak also 2.2 has auto activate) add cydia
      wifi - have sim in
      load yellowsn0w
      reboot
      5 dots toggle airplane on/off and then Searching then carrier
      I have found if you have weak signal you may have to try many times.

      Updated just did this method on my sisters 16G 3G iPhone that hasn't been working. This is Tmobile USA. Now outgoing calls work with no issue.

      uninstalled yellowsn0w 0.9.4
      reset network settings
      reboot
      installed yellowsn0w 0.9.5
      reset network settings again
      airplane off... about 5-10 secs ... airplane on
      Searching then Carrier

      This is what worked for me!! Thanks again to MODMYI for the firmware!!
      didnt work bro but thanks

      Guys, this is my success with the newest USA T-mobile Sim.

      I was having trouble with signal dropping with outgoing calls on 0.9.4. After the upgrade I couldn't get 0.9.5 to search for signal. Below is all the info I can think of that might help.

      My Sim 4 rows of numbers with 5th row vertical (no version #)
      0.9.5 would show invalid sim.

      Uninstalled yellowsn0w

      I reset settings and used my wife's sim 5 rows of numbers 6th row vertical (version 39.01a) Installed yellowsn0w.

      Worked perfect. Everything worked.

      I then put my sim back in and everything worked.

      I don't know if it will lock up again when I reset the phone, but for now the newest T-mobile sim is working.

      Remember, it is beta. Submit your report to the Dev Team and I'm sure they will have a fix posted ASAP...

      I have had my disagreements with him but he has had a lot of people hit his thanks button so he must be helping out somewhere. He speaks his mind and doesn't hold punches. I agree that the initial release of yellowsn0w was bad for t-mobile users. How can anyone argue that the initial release was a success? I am happy that the new update seems to be giving everyone back an operable phone. Good day.

      I uninstalled the ones that quit, plus that ones that work and just started a fresh, all of them work except for phone zap, there must be an issue with it or something, but everything is working nicely

      thanks for the help

      thanks to the Dev's for the wonderful unlock, working perfectly for 24hrs now...

      Thanks man, people know deep down that 0.9.1 was a complete EPIC FAIL! They just wanna try to act like girly nut swingers and cover it up.


      BTW be careful dude someone might try to cover your mouth for saying what you wanna say.
