August Wind Software's Mobile Adapter Tool provides an easy way to generate the SharePoint entries in the Compat.Browser file and the web.confg file necessary to use your own custom Mobile Adapter.
Not only can you generate and insert the entries, but you can install your Mobile Adapter DLL into the GAC without having to leave the application using a command prompt doing it by hand.
