I began an iPhone project the other day with a silly development code name, and now I want to change the name of the project since it's nearly finished.

But I'm not sure how to do this with Xcode, trying the obvious of changing the application's name in the info.plist file, causes the signing process to go wrong (I think...) and my app won't launch giving me a Launcher error.

I guess I could make a new project and copy paste everything over, but it seems so primitive that I'm hoping for a more civilized solution.
