Earlier quoted context omitted.
I had an early smartphone, the Sony Ericsson P800, and it was a full screen and the home page was a grid of app icons. The iPhone design was extremely well done in comparison but hardly some radical unknown thing. The real design innovation was the capacitive touch screen
I’m sorry, but I’m not sure how you think the p800 looked anything like the iPhone, https://goo.gl/images/t3XvMA Yes, they are both rectangles. But there were massive differences aside from the capacitive touch.
Parent post didn't say the phones looked the same. The iPhone refined a lot of existing functionality.
