  • [ 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.

      hi to all,
      I have been trying to jailbreak my iphone3g again using quickpwn on a mac, but as quickpwn goes through and tells me to go into dfu mode (I foolowed every step of it), quickpwn seems to just get stuck and all it does is tell me that quickpwn is getting ready to run on my 3g and that is it. I tried leaving it there the whole night and still nothing happend. Oh, this is the first time I used quickpwn because my pwnage didnt work either.
      Thanks in advance

      Why do you ask for help but not say what network you are on and what you have tried?

      Different things work for different networks.

      I am quite surprised that mine works at all as the apn/user name and password are all blank but I have full 3G access on T-Mobile UK but do have to do the Airplin mode toggle when I reboot.

      On 3G or 2G? if you get more on 2G it suggests the aerial is better. if it's on 3G it's because they are completely different masts.

      Listen everybody !!! Your APN is assign by T-Mobile. They use several different domain names, epc.tmobile.com is one, internet2.voicestream.com, internet3.voicestream.com are others, and there are even more. This is a fact!!!!

      In order to get Edge/Internet you must set your phone to the correct domain name.

      Call 611, say 'BlackBerry' at the voice prompt and you will be connected to the correct department. Ask what's the correct APN for YOUR account.

      You might get something or it might work for awhile by using a non-assigned domain, but it will NOT be reliable. One day in the not-too-distant-future, your internet access will just stop working and you'll be pulling your hair out figuring out what happened.

      I had a heck of a time for 3 days. I finally restored 2.2, only unlocked and installed Cydia and Installer. Nothing else. I then updated to
      Yellowsn0w 9.5, and rebooted. Now everything works except for popping out/in sim. I can live with this, it now swaps antenna's properly so calls don't drop.
      I have slowly reinstalled all apps and kept rebooting to verify the phone will get signal, make calls, and Internet works. All in all, I am still interested in the next version, but have a million percent better feeling about the phone at this point. I tried early on to uninstall Yellowsn0w and use a sim card ver. 2.2, to no avail. It wouldn't hold a signal at all and only exacerbated the issue more. Good luck to all. Not that I have any guaranteed outcomes, but I gave up and restored 2.2 again, as I said initially. When you think you're about to throw the phone away, restore it and reset all phone settings. What's the worst thing that can happen? It's already dead. That's what I did. Good Luck, and Thanks a million to DEV-TEAM. Wonderful job with the updates. I know each one of you are working tirelessly thinking this is all your fault. We all chose to do this, you didn't make us. Great job fixing the issues.

      I have read many messages where T-Mobile users having problems with the yellowsn0w unlock, reported what version their T-mobile SIM was, like 39.1?

      How do I determine what version my T-Mobile SIM is? My T-Mobile SIM is between 2-3 years old.

      Don't matter what sim card you have now,the newest one which did not work for out calls before now does work,and before only the old versions were working,so now it all comes down to

      A:your doing something wrong

      B:THE devs still have little bugs to fix

      mines work great now on the newest tmobile sim out calls and all unlike before.

      When changing back to AT&T:
      1) Need to Reset Network Setting
      2) Turn on 3G
      3) Play with Airplane Toogle

      Should work with that.

      I had better result when install yellowsn0w for the first time, when rebooting the phone thru SBSetting, I take out the SIM until power back on, slide to unlock then put SIM. Take just a little longer to get signal but work good with both T-Mobile and at&t.

      Hope this help

      Make sure your edge if off, sometime BossPref is unable to shut edge off so double check.

      Congrats on the unlock.

      I followed the instructions to the letter and everything worked absolutely fine, right up untill I had to make or receive calls.

      I'm on o2 in the UK and found after doing this my calls were failing 90% of the time, people were ringing my landline saying they couldnt get through to my mobile. I don't know if any one else has had the same issue's? It was so bad I had to restore and leave it (not even jail broke it yet).

      So the problem is either with the new 2.2 jailbreak or yellowsn0w? ...well in my case it is anyway. Hopefully someone will read this and know if its a problem with the software or not.

      Cheers.
