This o­ne's for our European visitors to this site. I noticed an article today over at ASCII24 [1]  where they had a bunch of pictures of the new vodafone "flagship shop" that opened up in Shibuya recently.
I won't go into much detail unless someone requests it, but the 5 story building is much more than just another shop to get/change your phone. You can try out contents, get accessories, etc.
Take a look at the place o­n this page [2].
