Sony technical support would not answer my question about the fact that units are hitting the street with different firmware. They just said that the one I have is the latest release. It may have something to do with the image they use in manufacturing. Maybe a release that only differs by number & not any code difference??? Do you know the release date on yours? I don't know how to get that info. Hopefully it means that a new release is coming soon. Provided it enhances some function!
Cheers,
