    Hi all,
    I was just trying to Jailbreak my iPhone 4, because I accidentally updated to 4.3.5. when I follow the steps like changing the Hosts file and using tiny umbrella, nothing helps! I try to downgrade to 4.3.4 and when I try to do so, iTunes prompts me that there was an unknown error (1604) or (1600). I REALLY NEED TO FIX IT! I have tried pwnage tool and everything! I am running Lion, and I hate it tbh!

    Do you have blobs save? if not, you can't downgrade firmware on your phone, the only option is to upgrade to OS5.

    Download Tiny Umbrella, run it and hit "Save SHSH".

    For your phone, the only option now is to upgrade it to OS5.
