I've been reading this news of the 4.0 update being available "from today" or "available now" for a couple of hours. So far however, the U.K Napster download site is still serving up ver 18.104.22.168.
This may no longer be the case tomorrow morning I suppose, but to be told over and over again in press release and news story that I can get something now and yet not be able to makes me feel like the U.K is getting a little looked over by the people.
Hopefully it's all just a time zone thing and the announcement will spread over to the U.K tomorrow. Here's hoping :-)
