I need built application about Windows Mobile development using Visual Studio 2005 or 2008. But now I need a documentation about Window Mobile development. I need something about:
1.) What is Windows Mobile Development Kit?
2.) What are the hand-phones (brand and models) that we can use?
3.) Currently, what kind of applications that is in the market that is using Windows Mobile Development Kit?

Does anyone could help to find this document?

Thanks
