Actually in the early days of the iPhone even Engadget didn't count it as a smartphone because it didn't run apps. Of course this changed later. What was considered a smartphone was mostly a Palm Treo, Motorola or HTC device. Some had Windows CE some had other OSes. The real addition of the iPhone was that while everyone was focused on features that they could sell to geeks and executives, Apple focused on consumer level usability. In other words, iOS did NOT beget neither Android nor WP7 but showed the industry that there are other important things that drive success.
