What I don't get is the idea of theft.. Of course it cannot be code theft. They are different implementation of an idea. It could be that the idea originated in the iPhone, but if the customers ask for a virtual keyboard, for example, are they supposed to restrain from implementing that feature because it was "not invented here"? Quoting from George Bernard Shaw: "If you have an apple and I have an apple and we exchange these apples then you and I will still each have one apple. But if you have an idea and I have an idea and we exchange these ideas, then each of us will have two ideas."
