Facebook customization, iframe/app vs fbml

I'm experimenting with facebook customization and was wondering what other peoples experience of the iframe/app route is.

Having constructed a page and an app (using a template) containing the content I find that the default page view is the wall and there seems to be no way to default to the app content. The iframe/app route also has a separate like button to the page.

Is there anyway around this or is this the normal customized facebook user experien开发者_JS百科ce, or have I taken the wrong approach? Does FBML offer a richer experience.

You can set the default page for non-fans to be the app content in the page settings. For people that are already fans, they will get the wall tab.

I think that it isn't. Maybe you could try static FBML ?
