yellowsn0w can now be considered stable

Author: Pico  //  Category: General, Jailbreak

Thanks to the hard work and dedication from the Dev-Team, the iPhone 3G’s software unlock solution is near completion and quite stable. I have been following forum posts from hackintosh, modmyi, and howardforums and the consensus is pretty clear it works for 95% of the people around the world using different types of sims and carriers.

Before yellowsn0w, I used the “Virgin-Sim” sim proxy, and it worked quite well with T-mobile USA. When yellowsn0w was released on New Years Eve, I disregarded reading any forums and continued to restore my iphone to 2.2 (I was at 2.1) and install yellowsn0w. To my disappointment, it was a pain to get working (multiple reboots, airplane mode toggling, and sim removal and reinsertion).

yellowsn0w version 0.9.6 has seemed to solved most of the problems others and myself have experienced. No longer will you have to remove or insert the sim or toggle airplane mode to get signal. The Dev-Team is still working on issues with Sim Pins and such, but it cannot be long before they crack that problem. Unlocking the iPhone 3G can’t be any easier:

  1. Restore your iPhone to version 2.2 (Not needed if you are already at 2.2)
  2. Use Quickpwn to jailbreak your iPhone
  3. Load up Cydia and add the yellowsn0w repo: Cydia source: http://apt9.yellowsn0w.com or Installer repo: http://i.yellowsn0w.com
  4. Install yellowsn0w
  5. Disable 3G and Data Roaming in Settings -> General -> Network (Step is mainly for T-Mobile USA whose 3G bands are not compatible with the iPhone 3G’s)
  6. Reboot the phone and you should have signal. I have tested yellowsn0w on my 4 year old T-Mobile Sim and a half year old sim, both work perfectly.
  7. If you have T-zones, you can get unlimited data by entering the APN: epc.tmobile.com in Settings -> General -> Networking -> APN

I was going to write up a guide and summary for the Sim-proxies\turbo sims that did work with the iPhone 3G, but now that is not necessary with a soft unlock. Remember, when a new iPhone 3G firmware comes out, do not upgrade right away. Wait until pwnage from the Dev-Team to disable the baseband update, or a version of yellowsn0w that does work with the new version of the baseband.

Kudos to the Dev-Team, thank you for this Christmas\New Years gift!

    Is it ok to update my macbook from 10.5.5 to 10.5.6 ???? I tunes is at 8.0.2. If itunes gets updated will devteam or someone say that it is ok to update?????

  2. mark Says:

    Yes it is.

  3. confucious Says:

    As you say, step 5 is not necessary for people not using T in the US.
    I’m on T in the UK and Yelowsn0w has worked since 0.91 but always with some messing around. Now with 0.96 it just works! no need to think about it, it just works as soon as the phone starts and all features (incl 3G in the UK) work fine.
    Some people have problems with Original (eg AT&T or O2) SIMS so need to use the BigBoss Toggle – is this going to be available for SBSettings?
    The Dev Team have done a fantastic job :)

    You can update but you will need to apply the DFU mode fixes otherwise you will not be able to use DFU mode to jailbreak or restore again.

    Hi..yellowsn0w worked great yesterday. Popped in a friends T-Mobile SIM worked instantly. Last night, however, I tried my TM SIM card and no luck or service. IT does have a 37 in the vertical row. Has this been addressed? ANy suggestions would b greatly appreciated thanks for that!!

  6. mark Says:

    I applied none of the “fixes”. Just follow the prompts via QuickPwn to enter DFU.

  7. mark Says:

    I have a 37 series SIM and mine worked with all versions of yellowsn0w.

    THanks Mark!..So I should just do the normal re-boot stuff, take out the SIM and etc..? And heres a stupid question.(sorry in advance)..how do I get charged for this?..do I have to set up an acct. with T-mobile?. Im going to South America and need some advice..much thanks again!

  9. Pelaez Says:

    There’s an update that with which the computer doesn’t detect devices in DFU, so putting the iPhone to DFU doesn’t work, there’s a fix for it though.

  10. ranova Says:

    yellowsn0w has been reported to work with all the old and new tmobile sims

  11. Scotch Says:

    I tried asking this in a general BB forum but no reply: are you working on a yellowsn0w toggle for SBSettings?

  12. ranova Says:

    there is already a toggle for SBsettings in cydia

  13. Anonymous Says:

    I use the SBsetting toggle for yellowsn0w…does anyone have an answer for me?”And heres a stupid question.(sorry in advance)..how do I get charged for this?..do I have to set up an acct. with T-mobile?. Im going to South America and need some advice..much thanks again!”

    I too was a beta tester fir virgin sim proxy and loved it. Was the best proxy sim on the market. When yellowsn0w debut, I held off after reading that over half of the us tmobile population was having problems and I have a newer sim so I would have been screwed. After 0.9.6 was released it seemed that 95% users reported success so I gave it a try and it worked perfectly. I’ve unlocked 3 iPhone 3Gs for tmobile and not one has had a problem. That is dev team! I wish I could donate for your efforts!

    Can quickpwn activates the iPhone 3G 2.2

    I’m going to buy an iPhone from Hong Kong and I wanna know if quickpwn can activates it… In my country, I don’t think iTunes can activate it… Some help will be appreciated ;)

  16. ranova Says:

    Yes quickpwn will activate your phone, just follow the step by step above and you should be golden

  17. d4rklamp Says:

    Thanks for your reply… I was asking this as I couldn’t find the activation window in all tutorial about quickpwn ;)

  18. mark Says:

    I am on 10.5.6 and don’t need to use these RIDICULOUS “fixes” is my point. Try following the prompts in the program to lead you by the hand through setting up DFU mode.

  19. Qbik Says:

    IS there a plan to made some switcher for SBSettings to on and off Yellowsn0w if there is possibility to switch it

  20. kittycat Says:

    yellowsnow works good, now my phone fuction without turbo sim. but my cydia hangs when i update the essential upgrade, and some of the app are not installing. any help? thanks dev team you rock..

  21. ranova Says:

    do a full restore and try again, it has nothing to do with yellowsn0w

  22. kittycat Says:

    ranova thanks for the tip but i’ve done that already and still cydia wont function right. i have to look & browse for answers, thanks mate…

  23. Asdrubal Says:

    I´m a complete newbie, and have managed to jailbreak my 3G. I cannot find the “yellowsn0w” to install either in Cydia or Installer. Could someone give me instructions?
    I did download the “Boss Prefs” and there´s a slide for yellowsn0w, but it´s greyed out.

    Many thanks in advance.

  24. Pdex Says:

    Does the data services like safari,etc work on am unlocked phone with tmobile. Just wondering before I do this?

  25. Dave Says:

    Hi,

    In the quickpwn tutorial on this site, it says that quickpwn will NOT activate the phone.

    I’m getting one soon and was wondering which answer is right.

    WILL IT ACTIVATE IT (Get it out of “emergency calls only” screen)?

    Thanks.

  27. Dave Says:

    I’ve heard some people have failed when installed using cydia, but were successful when installed through INSTALLER.

    Installer repo: http://i.yellowsn0w.com

    Try that maybe?

    Good Luck!

  28. Adel Says:

    but for your info. i found the when i updated the cidya and the i installed the software unlocking package again from the cydia (apt9.yellowsn0w.com)

    can i downgrade yellowsn0w from 0.9.7 to 0.9.6 i am on 3g 2.2 not 2.2.1, since i think 0.9.6 is much better

  30. Tm in China Says:

    I updated to 0.9.7 from 0.9.6 and now have to re-set the network setting each time I turn off the iphone. It shows “invalid sim” when I turn on the phone. Then I have to re-set the network setting. Could anyone help me get back to version 0.9.6? Thanks.

    I am extremely fluent in unlocking these iPhones and recently the yellowsn0w repository in cydia seems to be failing to add. I keep getting the response of “Did Not Find Repository” followed by some other things. Is there something wrong with the repo? Anybody been able to successfully unlock using yellowsn0w as of 3-30-09?

  36. Junoon Says:
