Unless I'm forgetting something, animating latitude and longitude wouldn't make the image appear to be spinning,
Your best bet is to follow the example, or, for a better effect write some code using a 3D library.
I know Papervision has a built in sphere object, and I'm betting Away3D does too. Animating a globe like that would look MUCH better, and you wouldn't have to come up with a complicated .fla setup.
