Assuming that Samsung came up with the ideas, there are any number of reasons why they didn't produce the iPhone. It takes a lot more than innovation to make a product successful. Marketability, both to the consumer and distribution channels, is a major factor. For devices such as smart phones, having the infrastructure in place matters a lot too (e.g. cellular networks capable of handling the bandwidth).

I am also getting tired of people claiming that Apple is innovative. They do things better than many of their competitors, especially with respect to marketing, and to a lesser degree with product development. Yet I would be hard pressed to call putting components from other vendors, for their intended purposes, innovative. Even the designs aren't terribly innovative. Most of the software UI elements have existed for decades or were implemented ad hoc. Things like case designs have more to do with trends and constraints placed by engineering considerations than anything else.
