How do I stop Yahoo from sending me SMS Horoscopes?

(My Original Blog Post: http://www.latesttrendsguide.com/?p=729)

4 years ago i gave them my cell # and horoscopes have been sent to be at 2:15 every day since then. I want to stop them, but I have no idea how, and the only thing on Yahoo! Help about SMS is about yahoo messenger. How to I cancel this stupid subscription? Thanks!
