Thread: Need help jailbreaking 3G[S] with iOS 4

    Question Need help jailbreaking 3G[S] with iOS 4
    Hi All,

    I have often jailbroken iPhone before but now I am having some troubles jailbreaking an iPhone 3G[S].

    I can't tell if this iPhone has been jailbroken before or not. For the moment, it was stuck in restore mode on 3.1.3, I restored it on iTunes to 4.0.

    Now of course, I am stuck on the Connect to iTunes Sim, waiting for a sim to activate the phone.

    I would like to know how can I, if possible, jailbreak this iPhone. I don't know how to check for the bootrom, but f0recast gives me the following infos.

    Thanks you all in advance for your help...

    It would seem forecast is wrong, if your on 3gs 4.0 and want to JB you need to be able to do 2 things:

    1. Have an old bootrom
    2. Be able to downgrade to 3.1.3/2

    Thanks... I checked and my bootrom is: 359.3.2 ... So it's the new one, isn't it?
    Then I have NO solutions for jailbreak? Or even just activate the phone without the sim card?

    No JB for 4.0 on new iBoot unfortunately.

    I am assuming your unable to downgrade to 313/2 then?

    Also to activate, you need a valid sim, borrow/ebay one i guess

    To be able to downgrade I should have done the SHSH thing? If yes, I didn't...

    Yes, I think I'll buy a sim from eBay!

    Thanks for your help dude!

    Guys I have the same problem. I have 2 3gs with i0s4. it has the old bootrom. I can't seem to downgrade it nor jailbreak it. I used pawnagetool 4.01 but no luck. I am always getting error 1600-1604 or 3914. I tried to put saudik server on the hosts file, but i am not sure if it is working. Another phone is stuck in the recovery mode and I can get it out now. Please tell me what to do, or how to proceed. Thanks.
