If you build a Web application in ASP.NET, it can be browse from any of these mobile devices using a Web browser (all of them have a Web browser).

But if you want to build applications for iPhone, and other mobile devices, you need to use their SDKs. For example, you need to use Mono Touch to build iPhone applications and andriod SDK to build droid applications.

Here are more readings on Mono Touch. See Blogs.
