For the iphone, you can launch the Facebook app if installed by using a url starting with fb://

More information can be found here: http://iphonedevtools.com/?p=302 also here: http://wiki.akosma.com/IPhone_URL_Schemes#Facebook

Stolen from the above site:

• fb://profile – Open Facebook app to the user’s profile
• fb://friends – Open Facebook app to the friends list
• fb://notifications – Open Facebook app to the notifications list (NOTE: there appears to be a bug with this URL. The Notifications page opens. However, it’s not possible to navigate to anywhere else in the Facebook app)
• fb://feed – Open Facebook app to the News Feed
• fb://events – Open Facebook app to the Events page
• fb://requests – Open Facebook app to the Requests list
• fb://notes - Open Facebook app to the Notes page
• fb://albums – Open Facebook app to Photo Albums list

To Launch:

NSURL *theURL = [NSURL URLWithString:@"fb://<insert function here>"];
[[UIApplication sharedApplication] openURL:theURL];
