The Footnotes.. 1. Yes, I know about the LG Prada That’s why I said “nobody used” as opposed to “none existed” 2. And the end of skeumorphism does not mean flat design; things like gradients and shadows have their place

I did read the footnotes, that doesnt mean the statement was invalid, so there author is treating iPhone as a synonym for smart phone, or there was somehow another iPhone before the first iPhone.
