Launching native apps with openURL

openURL helps you launch Maps, SMS, Browser, Phone, and even other applications.  This is one area of iPhone development that I always have to look up again when I need to do it and it is only one line! 

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://8004664411"]];

This app demonstrates the basic protocols supported natively on the phone.
