Hmm. "Photos" app won't rotate the picture being viewed when you turn the phone? The browser won't rotate if you open up the menu and go to "options", then "settings", and then check "Enable rotation"? Hmm. Nothing seems wrong to me here, though I am not really an expert. That is, I think, the correct file for the PR1.3.1 root filesystem. If you want to reformat absolutely everything in the N900, you'll also need to flash the "EMMC" as well; there's a separate .bin file for that. If you haven't already seen it, there's a page with a lot of info about this process at: http://wiki.maemo.org/Updating_the_tablet_firmware#N900 (This is another area where I am probably not the right person to say anything, as I've only flashed an N900 once...)
