Hm... but I guess they could overwrite the UK firmware with the US firmware using the updater (and the "version changing" updater hack) and then flash the Reader with igorsk's flasher. That should
But yeah, it would remove whatever changes Sony added to the UK version. To tell you the truth, I don't think it was any new functionality, but possibly something related to the Connect store, like disallowing UK Readers from loading books from it (for tax and/or contract reasons with Waterstones).
