Posting high scores from mobile app (CS5) to Facebook wall

Greetings–first post for me, found lots of great answers here over the years, and now I have a question I can’t seem to find an answer for.

I am using Flash CS5 to develop a mobile phone game app for android and iOS. The app is nearly complete and functions well.

The last hurdle is that I want users to be able to post their scores directly from the app to their facebook wall pages. I know this can be done from what I’ve seen in other apps, but I can find little to no documentation on it.

Most of what i read is for swf files embedded in html calling a javascript to post–but this will be running as an app on a phone, so they aren’t much help.

Any thoughts?

Thanks in advance!
