    Default [3gs] upgrade to OS4 from 3.1.2. with 5.12.01 bb
    Hey guys,

    is it possible for me to upgrade my 3GS to OS4 and jailbreak it?

    I have a jailbroken 3.1.2. firmware which I previously downgraded from 3.1.3. and the 05.12.01 baseband.

    so as for now it is jailbroken but carrier locked. I would like to have the jailbroken OS 4. Unlock would be great but not nesessary.

    It is jailbroken with blackra1n.

    Please Help!

    Thanks!

    Peter

    If you can start your phone without needing to run blackra1n every time, then yes, you can get to a jailbroken iOS4 by using pwnagetool.

    If not, you can still unlock your phone with ultrasn0w no matter which baseband version you're on.
