    I have a day one 3GS with the 359.3 bootrom (old?).
    It was running a 3.1.2 until the GM came out. The phone was jailbroken with 3.1.2.

    The phone has never had 3.1.3 or has been used with Spirit.

    My question is how do I jailbreak 4.0?
    Do I downgrade to 3.1.2 and jailbreak straight to 4.0?
    Do I downgrade to 3.1.2 and jailbreak that, THEN go to 4.0?
    Do I jailbreak just create a custom IPSW file with Pwnage tool for 4.0 and go ahead in recovery mode?

    Thanks in advance!

    Thanks for the response! Why do I have to go to 3.1.3 before 4.0 however?

    Faster just to jailbreak 3.1.2 with redsn0w then go straight to 4.0 custom.

    I've been trying to go from 3.1.2 to jailbroken 3.1.3 then jailbroken iOS4 but everytime I get to 3.1.3 I lose the network carrier. If I try going from jailbroken 3.1.2 to iOS4 I get an error 1600. Ideas?
