    Hi everyone, I still have my 3GS phone and I would like to jailbreak and unlock it so I may use it for international travel while my iPhone 5 can't be unlocked at the moment.

    The 3GS is currently on 4.0.1 and it's been jailbroken and unlocked. Now I would like to upgrade it to 5.1.1 but I wonder if it's possible as I haven't saved it's 5.1.1 blob (only have up to 4.2.1 blob)?

    The phone is with modem firmware 05.13.04 and serial starting with 5K01901. Any help on what are the appropriate steps to get this jailbroken and unlocked on 5.1.1?

    Thanks for your comment as any help is always appreciated. Have a great evening.

    At the iPhone hacks section.
    You need shsh blobs to restore to any firmware version that apple no longer signs.
    Check with tinyumbrella and see what firmware blobs you have available for that phone.
    Cydia pulls them for you automaticly so if you started saving them back from 4.2.1 chances are you will have them available for up to 5.1.1

    The iOS hacks section would be best for this type of question.
