It's called iMode here in Japan and almost every single Japanese has a portable telephone in Japan. Heck, My wife has one I have one, I'm surprised our dog does not have one. iMode has been around over here for years so in that respect Apple Japan is way behind the times here. Almost half of all the electronics stores on the net in Japan already have iMode (that's for all of the stores product, not just iPods), this is not news, they are way, way behind over here.
Then again if you have eyes like mine who can even see those tiny portable screens? However, almost all the younger people over here use their phones for email, telephones and shopping, not to mention games, cameras, it's their walking life. A lot of the younger generation over here just shut out the real world and are constantly playing with their telephones. It's kind of like Japanese portable telephone masturbation syndrome, hey it's a new disease JPTMS for short. I use it only for important business calls while on the move, otherwise it's done on a Mac, hey maybe I've caught MMS {Mac masturbation syndrome}.
