Thread: 3.0.1 to 4.0

  1. #1
    Default 3.0.1 to 4.0
    I just got a great deall on a 16gb 3gs on craigslist ($150!). its still running, 3.0.1, and I would like to get it to 4.0 jailbroken/ unlocked. I know this is the downgrading fourm, but i think this falls in here. anyways...

    what would be the process for upgrading the phone?

    would i go to 3.1.2 first then use blacksn0w, then use an pwned 4.0 ispw?

    how would i get to 3.1.2 if apple is not signing them anymore, would I have to use the old jailbreak tool on 3.0.1 first, then upgrade to 3.1.2?

    I dont want to do anything to it until I know I wont get stuck on 4.0 without the ability to downgrade.

    I apologize in advance if this is a repeat question, but ive searched this fourn pretty well, and i cant find anyone in my same situation.

    thank you!
