According to Nielsen( http://www.nielsen.com/media/2008/pr_080116.html), 46M people used mobile search in Q307. The interesting observation here is that most used Voice and SMS. I am assuming the 411 usage is voice with 18.1M users and SMS with 14.1M users. I found another piece of research that suggests only about 9M used mobile wap search in Q307.
