The idea of kids using their cellphones in class brought an article that Frasier Speirs wrote back in October to mind: http://speirs.org/blog/2010/10/9/run-what-ya-brung.html

He argues that there are a number of assumptions that come into play with using pupil's phones in this manner. He's worth reading, since he's involved in a project bringing tablet computers (currently iPads) into the school that he's working for and integrating them into their teaching. The entire series is fascinating reading if you're interested in mobile technology in schools.
