In February 2005, the late Apple CEO Steve Jobs gave senior software engineer Greg Christie an ultimatum to finalize the software for the upcoming iPhone or the project would go to another Apple team. Mr. Christie joined Apple in 1996 to work on the Newton and the iPhone project was important to him. The iPhone project was at that stage called project "Purple." Mr. Christie has never publicly discussed the early development of the iPhone before. Yet Apple made him available on the eve of a new patent-infringement trial against Samsung to highlight a key element of its legal strategy—just how innovative the iPhone was in 2007, when it arrived.
