Almost seven years into the life of the iPhone, Mr. Christie said one moment stands out. A few days before Mr. Jobs's keynote, Mr. Christie entered the auditorium through a side door using two separate security badges, then pulled back a thick curtain. He saw a giant image of the iPhone's home screen projected onto the screen in the dark room. At that moment, he said, he realized how big the phone would be.
“It was glowing in this huge space,” said Mr. Christie. “My heart skipped a beat and I thought, 'This is actually happening.'”
Interesting account from somebody actually there, and I love the photo of Apple's early iOS test setup.
