    so i have the iTunes version of the iphone iOS 4.0 firmware file. the "ipsw" to say, when i open redsnow and hit "browse" i get an error message saying

    "unable to recognize specified IPSW"

    im running this with the iPhone 3G. if you have any idea how to fix this it would be great! do i need to download another ipsw version of the firmware?

    At the iPhone hacks section.
    Try another IPSW download and make sure its 4.0 for your device and not 4.0.1

    IPSW should start with 1.2 for 3G
