    Ok, I like so many out there am struggling with what you can and cannot do and have a fear that if I do something wrong I will not be able to use my iPhone at all and it will become nothing more than an expensive paper weight!

    I wish to upgrade my iPhone firmware to a 3.1.x as there are apps out there I would like that require a 3.1.x firmware to run. Is this possible and if so how exactly can I do it safely without the risk of my iPhone becoming unusable? I could really do with some simple step by step instructions please.

    My iPhone:
    3GS 32GB
    Version: 3.0.1 (7A400)
    Model: MC133B
    Modem Firmware: 04.26.08
    Jailbroken: Yes
    Unlocked: No
    Cydia says I have SHSH's on file: 3.1, 3.1.2, 3.1.3

    My PC
    Operating System: Windows 7
    Since jailbreaking my iPhone I have changed PCs
    I have added the below to my hosts file gs.apple.com

    Your help would be very much appreciated
    Thank you

    google and download a custom 3.1.2 firmware and shift+restore to that in itunes and you are good to go..use either firefox or chrome to download it and make sure it was created with pwnagetool...
