you flash the nbh file, carriers only pack it in an exe so you only have to click one icon and your phone updates. i guess i dont know why you would want to flash an old rom on an alltel phone, there the only OFFICAL carrier to have rev a/gps radio right now in the states, and if you flash to a non-gps radio you can brick your phone... if you are using vista you might have a problem with ruu not working but there is a fix, please use the search for this.
