    Guys, i have a iphone 4 FW 4.0.2 BB 1.59 out of the box.

    And i have SHSH for FW 4.1 only.



    Is it possible for me to stay on BB 1.59 while updating to FW 4.1 ?

    I am asking this because of FW 4.1 will be jailbreaked and there is already an unlock for BB 1.59.


    Thanks for helping...

    I installed the 4.1 GM version and my Baseband didn't update.

    There is a way to install 4.1 without updating the baseband.. can't remember how to do it.

    yep this method works! i used this on my iphone 4 ... install the newest tinyumbrella and run the tss server... then restore to 4.1 and your baseband will stay the same

    My GUESS is that because the baseband on iphone 4 now requires shsh blobs (source theiphonewiki) that all you have to do to prevent the upgrade from happening is to simply not sign the baseband shsh blob.

    So ironically Apple made it easier for us not to upgrade the baseband

    but still be able to upgrade ios.

    But as I said, this is just a guess right now so don't take it as fact.

    So i can stay on bb 1.59 while updating to fw 4.1 and of course by not having the shsh for 4.0.2 ?

    basically so ... i would recommend to backup your current shsh blobs first incase you want to go back down
