trends in Japan

I think iPhone is trends in japan.
Many people use that include me.

I went to America in this summer vacation.
A lot of people use iPhone there.
I wanted to use that, so I bought it.
Half number of my friends who went to America, they bought iPhone after come back Japan!!
At Kwangaku, Many people also use iPhone.

So I think iPhone is trends in japan.
I hope it will not appear iPhone5, because I use iPhone4 :p
