  • [ 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.

      Jailbraking isn't a problem at all. You just can't use YellowSn0w (which is to unlock the phone to use on another carrier).

      Lots of info about your phone - which is good, but unfortunately none about your computer. I use windows so will point you in the direction of that...

      Look in the downloads section here

      For a MAC you could use either quickpwn or pwnage - quickpwn is nice and simple, pwnage allows you to customise your FW.

      Does anybody know if I have an iPhone with yellowsnow, is jailbroken and is on a o2 simplicity sim. Could I upgrade the firmware to 3.0, knowing that it would stop the yellowsnow working, but because it is on a o2 sim, would it still work???
    1. confucious's Avatar

      Yes it would - assuming, of course, that it's locked to O2 UK.

      Prior to going on o2 I used a turbo sim, when I was on 3 netwrok, the yellowsnow upgraded and I could just use the 3 sim on it's own. I later changed to o2 sim card.

      How would I knnow if it would work

      If it's a UK iPhone it will work.
      Where did you get it from?
      Simple way to check is uninstal/disable yellowsn0w - if it still works you're fine, if not just re-instal/re-enable.

      Thanks anyway

      You guys are awesome!!
      We truly appreciate all the efforts you guys have put into having the rest of us enjoy the iPhone.
      We hope that the new 3.0 brings an easier unlock for those of us who got an OOB 2.2.1 3G with BL 05.09, and cannot fully enjoy all the capabilities of what, for now, is just an expensive iPod touch.
      Thank you, and keep it up!

      Not necessarily - I've been thinking about this.

      If it is a UK phone then if you restore the phone and activate through O2 then jailbrake it should work. If your phone was activated via quickpwn it will not work with O2.

      To try you will need to restore a FW with BB 2.28.00 to make sure you can go back to YellowSn0w if required but if the phone is locked to O2 it will work.

      On the other hand, if you ever want to unlock you will need to keep BB 2.28 so what's the problem with using YellowSn0w?

      It bought the iphone on ebay and was informed it required a turbo sim. I don't know if it is a UK iphone or was bought in another country. I have no problems with yellowsnow, its excellent, but I was looking at the benefits of being able to upgrade my iphone with the latest firmware adn thus havin he additional extras when 3.0 comes out. My iphone us currently on BB 2.28.00. If I start from scratch and go via itunes update it will change the baseband and I will have no iphone for years How do I find out if it is a UK phone or a foreign import (also which country it is from). Also I have an idea on how to reset, but am uneasy at atviating through O2,as the last thing I want is a phone I can't use, so a "idiot" guide on how best to carry this out, would be appreciated.

      So long as you don't upgrade your BB you can still use YellowSn0w so, to keep it simple, do NOT restore to any FW other than 2.20
      What is your Model No? that will tell us if it is possibly a UK phone (the same model no is used in Ireland so not definitive but if not a UK model at least you will know).
      Trying to activate on O2 will not do any harm - if it doesn;t work you can still use YellowSn0w.
      So long as you make sure you don't upgrade your BB you will be OK.

      Thanks for your help!! The model number is MB489B, which I believe is Ireland/UK. If I'm on BB 2.28 How do I downgrade, to test if it will work. Also if it does, would I then be able to upgrade to 3.0, which will change my BB? My main aim is to allow my to update via iTunes anytime i.e when iTunes release the NEW and improved update with all the extras.
