Christie recounts how Steve Jobs was unhappy with the pace of the development, wanting ‘bigger ideas and bigger concepts’, instituting a deadline of two weeks before the project would get moved to another group of software developers. Christie was first approached by Scott Forstall, when he was asked to work on a secret project, codenamed ‘purple’. This would a touch driven phone that doubled as a music player.

His team was responsible for features like slide to unlock, making calls from the address book and the iPod app which would eventually become the Music app. They poured over details such as perfecting the scrolling speed of lists and the ‘bounce back’ when reaching the end of a list. Christie had meetings with Jobs twice a month, in a window-less room where very few had access and cleaning staff were not permitted.

In early 2005, Jobs gave the go-ahead to bring the iPhone to life. What followed was what Christie calls a “two and half year marathon“, with Jobs obsessing over every detail. The rest is history.
