    Default iPhone 3GS from 5.1.1 to 4.3.3
    Hi I was wondering if there is anyway for me to downgrade my iPhone 3GS from 5.1.1 to 4.3.3 without having the 4.3.3 ash blobs saved

    Nope...need blobs...old bootrom only comes into play as far as always being able to JB untethered...u need shsh blobs for the phone u r working on, for any version of iOS above 4.x

    Do you mean to downgrade to 4.1 stock firmware?

    No downgrade to a custom 4.1 firmware to preserve your baseband for unlocking purposes

    You can downgrade without needing any shsh blobs

    In my opinion it's the best iOS for 3gs

    Thanks a lot. Can I use the redsn0w to create a custom 4.1 firmware? If so, does it matter which redsn0w version?

    Thanks. What are the procedures I need to go through before the completion of downgrading jb iPhone 3Gs to 4.1 using either redsn0w or snowbreeze?

    use this guide here:

    Apple, iPhone and iPad News | ModMyi - How To Jailbreak Using Sn0wbreeze v2.9

    but make sure to download the sn0wbreeze v2.9.6 on ih8sn0w.com

    when you open sn0wbreeze, instead of clicking the "Browse" button like in the guide, you can just select "Download iOS firmwares", then select your device and select the 5.1.1 iOS firmware and it will download for you

    then proceed to the next steps

    another thing, when you get to the option that allows you to select "Simple Mode" or "Expert Mode", select "Simple Mode", and then there will be a POP-UP Message asking if you want to "Activate your iphone".

    Only click YES, if you DONT have an official sim card (like AT&T) to activate the phone

    However, if you click YES, you "MAY" lose GPS function and Push notifications

    if you have an official sim card, select No, then proceed onwards
