Here's a way to use the android/iphone Facebook app on wp7.

1. Download WizTiles from marketplace.
2. Open app and download "metro plus" theme.
3. Open metro plus theme and pin the Facebook tile to start screen.

this is fully functional..if your looking to replace the windows version of FB.

That isn't installing android/ios facebook app to WP7, that is a web portal

Sweet, then I can just pin it to my screen. I sometimes use m.facebook.com and it looks like a 90s site.
