I have a client who has video content for the web in Flash format.

Is is possible to create multi-colored text within a UILabel? I.e, if my text was: "The quick brown fox" have the q and b in blue with the rest of the text in black? I get the feeling I'd have to use a UIWebView and render the text in HTML to accomplish this. Thoughts? ...

Then have a UIImageView and UILabels for the thumbnail and main text ("All3Sports").

I'm working on a MKMapView with the usual colored pin as the location points. I would like to be able to have the callout displayed without touching the pin. How should I do that?
