and another thing...
Look Samsung, your smart-phones are a direct rip-off of the iPhone, more so than any other manufacturer. We all know it, and your denials show it even more.
Do you know what is not a rip-off? Look at Nokia's Lumina phones. Other than being rectangular, they do not look anything like an iPhone, and the OS is also completely different in appearance, features, and the way it functions. Sure you can do some of the same things, like Facebook, but the implementations are unique (quite unexpected from M$). So, yes, it is possible to design a smart-phone that is not a rip-off of the iPhone. You should try it sometime.
