According to the Wall Street Journal, Christie was originally hired at Apple in 1996 to work on the ill-fated Newton PDA. Fast forward to 2004, when Apple’s Scott Forstall pulled him into a closed-door meeting and asked Christie if he wanted to jump on a secret project to develop a phone with a touchscreen and an integrated music player.

Christie agreed to join the project, codenamed “purple”, and in the next year he and his “shockingly small” team ground out features we now take for granted such as the speed of scrolling lists, “bouncing back” at the end of a list, how to redesign text messages into individual conversation streams, and more.
He and the team made secret bi-monthly presentations to Steve Jobs, and eventually to other Apple executives, as well. Eventually designed Jony Ive was included, as well. Those working on the project had to keep everything locked down, including encrypting images of the project and preventing their families from seeing their computers when working at home.

Starting in early 2005, the iPhone project took flight in earnest, what Christie called a “two-and-a-half year marathon” to the finished iPhone, which was eventually released in 2007. The rest, of course, is history.
