A cell phone

I have a cell phone. Cell phone is very useful for me. For example, when I want to contact with my friends, I can send e-mail to them at once. I often consult with my friend in e-mail. I can say what I want to say. Also I enjoy listening to music in cell phone. My cell phone's sound is very clear. So I often take my cell phone to the bath room. I listened to music in the bath room. Cell phone is indispensable for human life.
