Looking at a diff between the last global & UK firmware, I'm even more confused. There's actually quite a lot of differences, most of which are utterly irrelevant - the names used to reference the default bookmarks change between the global & UK firmware, though the URLs are exactly the same; the XML code defining the internet radio stations uses a namespace in the UK firmware, but not in the global. I can see very little that's actually different, but a whole lot of stuff that's been changed for no reason whatsoever - are the UK firmware customisation guys just trying to make their jobs look more important?
