The iPhone Steve Jobs revealed in January 2007 featured a 3.5-inch plastic display. Not many people remember that, because the phone sold that June was covered in glass. The switch from plastic to glass appeared as a footnote in an Apple press release just 11 days before the original iPhone went on sale. What happened in the five months between has mostly remained a mystery, until now, thanks to a video surfaced by Dave Mark at The Loop.

The story is suitably recounted by Jeff Williams, Apples Chief Operating Officer, wholl also be responsible for software and hardware design when Jony Ive leaves Apple later this year.

As Williams tells it, the day after he held up the plastic iPhone on stage, Jobs complained to Williams about scratches that had developed on the iPhones display after carrying it around in his pocket. “We need glass,” said Jobs, according to Williams. Williams protested, saying durable glass wouldnt be available for another three to four years. “No, you dont understand, when it ships in June it needs to be glass,” replied Jobs, “I dont know how were going to do it but when it ships in June its going to be glass.”

Two days later, Williams received a call from Corning CEO Wendell Weeks. “Hey, your boss called and said my glass sucks,” said Weeks, according to Williams. Weeks then suggested using technology “sitting on the R&D shelf.” The Apple and Corning “teams scrambled” over “months of sheer terror” to make the “hail Mary” work. The scratch-resistant glass that shipped on the first-generation iPhone would eventually come to be known as Gorilla Glass.

Williams retelling took place in 2017 at Cornings factory in Kentucky where Apple announced a $200 million investment thats likely helping to fund the companys development of flexible glass for foldable displays. Apples rumored to be working on a device with a foldable display that could launch as early as 2020 — a product Williams is presumably intimately involved with.

Apple watchers have expressed concern over the future of Apple product design with the imminent departure of its Chief Design Officer. Stories have emerged of Jony Ive being dispirited by Tim Cooks lack of interest in product development. Simultaneously, were seeing evidence that its been
