Unable to add framework (MessageUI) to target

Question

Obvious question if you know what/where to look...unfortunately I don't...yet.

When I double-click my target and try to add the MessageUI framework it's not listed. I tried to do it manually and ran into trouble. I see that this app's target is for 2.2.1 and obviously MessageUI requires 3.0. Where can I set this? Do I need to create a new target? What doc should I read to understand this better?

I haven't had much need to separate the various OS's...until now.

Thanks...

Double-click the Project, go to General, and set the "Base SDK for all configurations."
