Sony's European blog has updated with news and links on how Europeans without credit protection can sign up for a year's free service. Its really unlikely you'll need it, but never look a gift horse in the mouth etc.
This follows on from Sony free games offer yesterday, all we need is PSP access to the store and the games to download, which should kick in over the next week.
On the subject of stores, whatever happened to PlayStation Suite? Sony is supposed to be unveiling something at E3, but its definitely on the back burner at the moment. With Xperia Play prices falling, could be a good time to get in there.
