IAds with Admob integration.

Has anyone successfully combined these two ad services in their app? If so, how difficult was it to implement, and do the ad services work well with each other? I’m thinking of adding Admob support in my game, but I would only like to do so if it is worth the effort as I don’t know how to add the code into my app right now. Thanks!

Sorry if this is branching off the Codea app, but I’m at my final stage in the app development. Everything is done, and I’m just wondering if this would be a beneficial thing to do–adding two ad networks instead of one.
