    If this custom IPSW was created with pwnage tool 4.0 there is an ibooks error, you will need to use one created with the newly released pwnage tool 4.0.1

    hi all,
    I have a 3gs running on a jailbreaked 3.1.2 (7D11) with baseband 05.11.07 an a serial starting with MC….
    Can I use the above mentioned custom ipsw for unlockers to upgrade to ios 4.0? Will the phone still be jailbroken and can I still use an unofficial carrier?
