    Default 3GS 3.0 to 4.0.1 upgrade - need help
    Hi,

    i've been searching for the best part of two days to find the info i need, so im finally posting a question.

    My current status:

    - iPhone 3GS
    - 3.0
    - SHSHs 3.1.2, 3.1.3, 4.0, 4.0.1 on file on Cydia.
    - Old Boot Rom
    - JB'ed with Redsnow (last year)
    - PC w/ XP

    I want to get to JB'ed 4.0.1. Can someone please tell me what i have to do, step by step if possible.


    Do i need to upgrade to 3.1.2 or something first?


    Many thanks.

    Just use a custom 4.0.1 firmware or create on yourself.

    custom doesnt mean its custom for me, just custom for JB'ed phones?
