Where is the documentation for Facebook Connect for Mobile Web?

Has any开发者_StackOverflow中文版one seen it? Facebook made big announcements in 2009/2010 about 'Facebook Connect for Mobile Web' but now all I can find are broken links to pages that no longer exist on the official Facebook blog and in the developer forums.

Examples: This blog post links to a page that redirects to the basic website documentation, not mobile web: http://developers.facebook.com/blog/post/299

And here is where the mobile web preview is supposed to be: developers.facebook.com/docs/guides/mobile/preview

The main reason I am searching for this seemingly non-existent documentation is to find out if there is a clean(ish) way of adding 'Share on Facebook' and 'Facebook Like' to a mobile web application that does not bring in the entire fb.js library or rely on fugly iframes.

Did Facebook silently give up on mobile web integration, or did they just move all the documentation to a place that isn't indexed by any search engine?

It has a link on the home page:
