This document discusses strategies for supporting iPhone, Android, and other mobile devices when customers are using those platforms but a company's existing development is focused on Microsoft technologies. It covers checking the user agent to determine the device, using mobile web frameworks like jQuery Mobile to create native-like experiences, consuming REST and SOAP web services from mobile apps, and tools for working with SOAP on iOS like wsdl2objc. The key recommendations are to use ASP.NET MVC with device-specific views for a mobile website, and to choose REST over SOAP when possible due to SOAP's increased complexity on mobile.
