The first phone model iPhone it was presented in 2007 by Steve Jobs with a plastic screen, something that very few people know. The first iPhone was launched with a glass screen, and what happened in the past 6 months from the presentation to the launch are a secret that Apple kept until recently.
After the presentation of the first model of the iPhone, Steve Jobs complained to Jeff Williams, the man in charge of developing Apple products, that the plastic screen was scratched, and that a glass one was needed. Williams said that this is impossible to change in just 6 months, but Steve Jobs did not agree, so he had a discussion with the boss of Corning, the manufacturer of Gorilla Glass.
Steve Jobs told him that the protective plastic for the screen is bad, and this motivated him to suggest Williams to use Gorilla Glass protective glass in the iPhone. At that time, this glass was just an unfinished project, but in 6 months it would become the protective glass for the first iPhone model.
Steve Jobs and Jeff Williams "pulled" Apple employees to implement Gorilla Glass in the iPhone screen in just 6 months, and Corning employees were very helpful. The iPhone was the first phone with Gorilla Glass installed, but even now Apple does not admit that it uses this protective material for the screen.
