    Hi everyone, after trying to get my 3gs unlocked and jailbroken for quite a while using redsn0w to create custom firmware and restore I kept receiving an error. I figured a easy way to unlock the 3gs on ios 6 but it doesnt work if your iphone is not compatible with the ipad baseband. IPAD BASEBAND WILL BREAK GPS! We will be upgrading to iPad baseband than downgrading to 05.13.04 to avoid breaking gps.

    1. Download the latest iTunes and upgrade your iPhone to ios 6 through itunes. If this works skip to step 4

    2. If upgrade does not work, download ios 6 (link below) and than Put your iPhone in DFU mode (Google if you need instructions).

    3. Once in DFU mode, open iTunes and hold shift(Windows), Command(Mac) and point to the downloaded ios 6 firmware. This will give you ios 6. I had errors updating through itunes and itunes restore worked for me. If you can update directly through itunes that will work too.

    4. Once iTunes is done restoring, connect your iPhone into your computer and open the latest version of redsn0w. (Link at bottom).

    5. Once in redsn0w select jailbreak, and it will ask if your iphone is new bootrom, make sure to correctly identify.

    6. Put your iphone in DFU mode for redsn0w to detect it.

    7. After it has been detected, you want to check jailbreak and also install iPad baseband (since the baseband right now isnt unlockable)

    8. The process will begin and since this is tethered jailbreak after it is done you will need to go back into redsnow and select just boot (while your iphone is in dfu mode).

    9. Now that your iPhone is jailbroken and tethered booted, launch cydia.

    10. Once in cydia, go to manage than sources.

    11. Now select edit than add, and type "http://repo.iparelhos.com" than hit add source.

    12. After the source is added, search for ultrasn0w fixer and download it.

    13. Next in cydia search for ultrasn0w and than proceed to download that as well.

    14. We will now downgrade the iPad baseband. Open redsnow with your iphone connected and select jailbreak.

    15. Put your iphone in DFU mode and this time only check downgrade ipad baseband. Nothing else! Reboot tethered once again and your done!

    This will downgrade baseband to 5.13.04 and avoid any problems with the iPad baseband. I found this procedure to work easily as I and I noticed others had issues with the redsn0w custom firmware. Have tested working on iPhone 3GS! Thank you

    I also jail-broke my iPhone 4S by redsn0w jail-breaking tool. My colleague recommend me an official website of redsn0w and that provide me the jailbreak tool and it's installation guidance . Now, I can get all paid apps free of cost by Cydia. :apple:

    you didn't get the app to steel apps from the Dev-team they do not encourage pirating and this forum does not allow the discussion of it. Are you so cheep you can pay for a simple app most are less then a bottle of pop. :rolleyes: also there is no jailbreak for 6.0 for the 4S so the only thing you wanted to contribute to this is your nice coworker friend taught you how to steel.

    Modem Baseband

    Thank you for your guide, I would like to add the following, if you upgrade to IPAD baseband you WILL loose GPS functionality, downgrade the baseband to 05.13.04 and GPS will be back.. In general, it is better to wait a little longer to give the developers time to adapt their programs to the new IOS.. After that, you can use this guide.

    You might have to restore iOS6 to get it to work
