    Hi,
    I posted several threads earlier to fix 3GS and now with the help of you guys now manage to restore it to 4.1 bb 6.15 jailbroken and working in normal condition.

    Now iot to unlock i need to downgrade bb, i have read several posts and even IC guide but still not sure about it. There are differences in several posts some says use the latest redsn0w while others say use some older version. And also some guide specifically mentioned to select the current FW and other did not mention about selecting FW.

    As mentioned above i have 3GS on FW4.1 BB 6.15.00, my serial #XX008. So is it safe to downgrade BB??

    I do not want to start it all over again. So Kindly request to assist me on this, with a proper guide.

    Thank you

    Yep, your device already has the iPad baseband - that is the only risky part (your device was obviously safe to flash).
    Downgrading the baseband carries no risk - tutorial on iClarified.com

    Taking a rubber band and wrapping around your phone should do the trick
