If you are building this on top of an ASP.NET site, then you should know that in ASP.NET you can check if the request is coming from a regular browser or a mobile device browser.

Request.Browser.IsMobileDevice

Yes, it does not work 100% of the time, but you can play around with that. This way you don't have to build a mobile solution from scratch, but just do the checking and redirect to a different set of UI pages designed for mobile browsers.
