yellowsn0w unlock iPhone 3G

Jailbreak | Hans | January 1, 2009 at 6:12 am

The DevTeam has released yellowsn0w, the world’s first iPhone 3G unlock. You must upgrade to the latest baseband 02.28 in order to use it. It is possible to use it with the older baseband on firmware 02.27 but the DevTeam has exclusively restricted it to work with the newest baseband. So if you haven’t already, upgrade to firmware 2.2 with the 02.28 baseband! Did you unlock your iPhone 3G? Post back your results here and let everyone know of the experience. From what I hear it should be a very simple automated process. You can download yellowsn0w from Cydia/Installer.

    BE CAREFUL – I used this jailbreak soloution on 3 seperate computers, I seeked assistance from the ‘team’ which was slow and misleading.

    I have tried for days to get a refund and nothing is happening.

    I am a web designer and I’ve been around computer all my life – So I am not just stupid!

    It may well have worked for some people, but I think these comments below are scams.

    YOU HAVE BEEN WARNED!!!!!!!

    I had my Globe locked iPhone 3G unlocked by a mobile phone technician. It was on “NO SERVICE” or there is no signal from any Philippine network since. What should I do?

    FOUND THIS and IT WORKED for ME… I wasn’t successful the first time, done it 3 times and it worked. Fonts was too small that’s why i had so much typo while doing it.

    This is for changing the baseband of your iphone without going through the whole restore process.

    1. Download Mobile Terminal from Cydia.
    2. Download the file from the link at the bottom of this post, uncompress it and upload the files via SSH to /var/root/
    3. Open Mobile Terminal
    Note: You can only use this program. Don’t use mac terminal as the iphone will be disconnected in one of the steps
    4. Type in: su
    5. Type in the password: alpine
    6. Type in: cd /var
    7. Type in: cd root
    8. Type in: chmod 755 BBUpdaterExtreme
    9. Type in: launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist
    10. Type in: ./BBUpdaterExtreme update -f ICE2_02.28.00.fls -e ICE2_02.28.00.eep
    11. Reboot your iPhone
    12. Now your iPhone must be in the 02.28.00 baseband! You can check it in Settings>General>About.

    Hello Green Tiger

    I’m running on Firmware 2.2 baseband 02.30.00, I have tried the above method hopping to downgrade the baseband to 02.28.00, so I would be able to use yellowsw0n.

    after running the code, and rebooting, my iPhone is still running on baseband 02.30.00, is there any other way to downgrade it ??

    Thanks
