Jeez - this is the third time I've seen this question in the last two days (and I might even have missed some) - Is there an SMS code competition on that I don't know of?
Anyway, I know that the other two questions have received good answers, so maybe you could use the search function and find them?
Or simply browse the questions from the last two days and you will find them.
[EDIT]
Right now I see a post with THREE answers just 10 or 15 post further down on the same page as this one. This will of course change in a while...
