This way, you can validate each time the app is run, you are validating constantly, and you can also have complete freedom to change the way it works on your server without messing with the iPhone app itself.
This is how all MMO games work, but it's probably not worthwhile for 99% of simple iPhone apps.

Not quite. Each game is sold with a unique identifier (cdkey), and this identifier combined with the fact that the game is played off the server makes it unsuited for piracy.
On the iPhone, we can run everything off a server, but we have no identifier that can help us identify legit purchasers from crackers, so we don't know who is pirating and who isn't.
