    Default How do I upgrade already JB 3GS from 3.01 to 4.0?
    I jailbroke and unlocked my 3GS using redsn0w 8.0
    Used f0recast to check everything:
    Baseband 04.26.08
    Bootloader 6.4
    Firmware 3.0.1
    Model MC143
    Jailbreakable: yes
    Unlockable: yes
    Untethered: yes

    So, what are the best steps to upgrade?

    save your shsh in cydia. Next upgrade to 4.0 using legit itunes upgrade. Use redsn0w to j/b and ultrasn0w to unlock
