about my keitai

I'm going to introduce about my keitai. I'm using a Smart Phone of Docomo. Honestly, it is difficult to use. I want iPhone. Because there are a lot of pretty coverings for it. But my family's keitai are all machines of Docomo. So, I can't change different company's keitai. Because I can't call free calling among family if I change different company's keitai. And I'm going to wait untill Docomo sell iPhone. I have been used the folding keitaifor three years before I bought a Smart Phone. It was very easy to use but sometimes it broke. Color was pink and it was very girly. And I thought that colorful keitai is fed up soon. So, my Smart Phone's color is black.
