I have just started authoring web pages for use on "smart phones". I need to target Blackberry, WinCE, iPhone, etc. What resources or books would you recommend for someone with ample web and software development experience but no experience developing UI for these devices? What emulation kits would you recommend, and how accurately do they represent the real thing?
Edit: To clarify, I have a web application built in ASP.Net. I want a limited subset of the functionality available in the app to be available to mobile devices. I am writing a separate set of pages to accomplish this. I am starting with two, simple chunks of functionality. In the future I believe I might get requirements for more functionality to be ported.
