Erm. I don't think this is a Codeigniter question to be fair.

Sub-domains are set up in your web server of choice and DNS not Codeigniter, although I'm sure there is a way to achieve changing it with CI, if that is what you want?

You have to configure your vhost/apache/httpd to forward all calls for pages to something.example.com to e.g. example.com/page/something. From there on you only need a controller page that takes care of the rest. But the main part is to configure your webserver appropriately. Google for something like "dynamic subdomains". I know there is a tutorial on net.tutsplus.com that covers this topic but not for codeigniter yet for some other webapp (forgotten the name).
But hey: Just be creative with your google search queries
