Can Cellphones Be Educational Tools?

I think cell phones will eventually be used as major learning tools. Last year in a math class, my teacher asked us to pull out our cell phones and send a text to a certain number answering a poll question. The answers were sent to an online website that was able to gather all the data and put it into graphs. The cell phone number was next to each answer so the teacher was easily able to identify who was who. This method of teaching was really cool because it was so different. I think cell phones could be a really good teaching tool, however i also think they could be distracting… it all depends on who you are and how focused you can be. My phone is used as a calender for me, i use the calculator all the time and constantly safe homework assignments on it.
