  • [ 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.

      this site is a worldwide site. i don't want to pigeon hole all of you into the stereotypical view of americans but after reading this thread entirely, the world seems to have declared the 3g unlock as a success, whilst t-mobile USA customers with new sim cards have deemed it "not ready for public use" and "fail".

      Think outside of the US guys! There is a world of happy people with unlocked iPhones around you. Don't spam with selfish posts!

      To finish - works perfect with Orange UK no problems on 16GB iPhone 3G after using the pwnagetool as opposed to quickpwn. no signal after using quickpwn here....

      Testing carrier in Central America.

      - After several tries, I finally got the Carrier to Show up, full Bars. When I tried making a call, I got a "Call forwarding message" I got the tone and then it hung up and I lost all my signall bars, but the carrier is still showing.

      Any ideas?

      I still don't understand one thing. In most of the countries everything works. The Dev-Team practised their unlock on T-Mobile USA. How is it possible that we have a lot of problems with this network...

      as the dev team consists of members from around the world im sure they don't solely test a worldwide 3g unlock only on the t-mobile usa carrier.

      i hate to break that to you.

      i also heard - they MIGHT not even be american.... imagine that

      If I walk into some Walmart/BestBuy store pick a new iPhone 3G 16 Gigs for $289 :P and come back home and if I don't want to Activate and pay the charges .. Can this be done?

      This means , If I buy a brand new iPhone 3G and I do not wish to activate it and pay the crap Monthly Charge can yellowsn0w sim unlock be done?

      First of all can an Unactivated iPhone 3G be jailbroken? If yes then we can connect via Wi-Fi to Install Yellowsn0w and Unlock it .

      Tell me if that is possible.
      Thanks.

      Umm I'm from Boston but in Hong Kong for Christmas break at the moment. Yellowsn0w is not working on my AT&T locked iPhone 3G, carrier CSL. I also see a lot of failures from German users who have posted on the iphone dev blog.

      this REALLY sucks.. restored to 2.2 quickpwned. cydia - yellowsn0w. Can't pick up any service so now I'm screwed. ALSO when I try to do airplane mode, it will be "searching" for maybe .2 seconds and then go back no bars. AHHH

      Im referring to this site and the posts in this thread deeming yellowsn0w a "fail". This is extremely misleading to readers from practically every country except america (t-mobile) customers.

      This site is a WORLDWIDE community. It's not fair that yellowsn0w is tainted as a "fail" when it has also been succesful around the globe.

      The dev-team didn't hide that it's in beta and anyone with brains would have held off for a day or so to let things cool over, like with new firmwares etc etc.

      Just sucks to be t-mobile USA ..... for now

      HAHAHHAHA ok i got back from the store and decided to give it one more shot. After following the steps listed several times here i had quit for the night but like i said after i got back i just wanted to try again.

      I inserted the sim, waited a few mins, airplane mode on/off and nothing... rebooted via Boss, waited several mins(4-5 ish) did airplane mode on/off and it actually said searching!!!!

      before it was only flashing searching and then it'd go to dots, this time it stayed up there saying searching, BAM full signal. i've made a 10 min phone call so far. received phone calls, Sent/received text messages. Edge works, wireless works.

      Everything works that i know of and i've not lost service so far.


      EDIT: forgot to add to this post, i'm USA T-Mobile. Everything is still working just when i reboot from installing apps sometimes i have to go do te airplane mode again but it works flawlessly other than that !!
