Q:

List of iPhone Applications that support openURL:

Is there a definitive (or otherwise) list of schemes that iPhone Apps support via:
- (BOOL)openURL:(NSURL *)url

A:

This appears to be a nice informal wiki of various custom-URL-supporting applications (although it is missing my own, as well as at least one other application that I know).   There is also this post. 

A:

Check out http://handleopenurl.com/ which contains a comprehensive and searchable database of URL schemes for the iPhone!  Much more comprehensive than my own list :)
