    Do you guys think it would be possible to unpatch the Spirit jailbreak in an iOS 4 ipsw then restore it with iDeviceRestore, then jailbreak?

    I thought with iDeviceRestore they didn't have to sign it.

    It doesn't need any signing. Even from Apple.

    So do you think someone could edit the 4.0 ipsw and jailbreak with Spirit?

    i used to decrypt the 4.0 betas and modified the plist for multitasking and wallpapers.

    But i could not rebuild the firmware back and itunes always returns an error.

    Well, it was beta 4.0 and I used decryption keys for the relevant beta dmg to decrypt it. I used vfdecrypt to decrypt the dmg with the codes released on the net.

    Go find the decryption keys and vfdecrypt tutorials yourself on google. I think this is illegal? But I don't think there are keys for 4.0 GM or final. Besides, I didn't know how re-encrypt it back and then recompile. I just zipped it back and renamed it to .ipsw and iTunes couldn't restore it, giving an error everytime.
