Here is a hypothetical situation: My wife and I have laptops. Her (crappy) music is on hers and my (sophisticated/diverse) music is on mine. We both purchase iTunes music on our respective computers, but use the same iTunes username/password. We both buy iPhones. She syncs hers up to her (crappy) Dell laptop and I sync mine to my (sexy) Macbook Pro. I purchase several Apps such as Super Monkey Ball. Since we are on the same iTunes account, can she get Super Monkey Ball on HER iPhone without us having to re-purchase it? Could I just copy the App file from my laptop and drop it in her iTunes App folder on her laptop?
