Steve Jobs' new biography reveals that Apple CEO Tim Cook still has not deleted Jobs' number from Cook's iPhone contact list.
The book titled "Becoming Steve Jobs" includes a number of untold stories about the former Apple CEO, who successfully marketed the first iPhone. It officially went on sale on Tuesday.
Cook saved Job's number as a remembrance from his old friend, who died of pancreatic cancer in 2011.
Apple agreed to participate in making Jobs' biography because Brent Schlender, the book's author, was friend close to them. The MacBook maker believed that Schlender will do a good job in preserving Job's legacy, according to IB Times.
To make the book, Schlender and coauthor Rick Tetzeli conducted interviews with several workers who worked with Jobs in the past, including Cook and Apple designer Jony Ive. Laurene Powell Jobs, the former Apple CEO's widow was also interviewed.
Cook was not the one who directly shared the story about Job's contact. Pixar Chief Creative Officer John Lasseter learned the story when he talked with Cook in a party in 2013 and shared it with the authors.
Lasseter narrated that Cook came over to him during the party. He asked Cook if he misses Jobs while taking out his own iPhone to show that he still has Jobs' contact in his list. Cook also took his iPhone out and also pointed to Jobs' contact number.
Parts of the book were teased through online news such as Jobs' decision not to make Apple produce a TV again, according to Venture Beat.
Schlender started his work in 1986 when he interviewed Jobs. In the new book, it is revealed that Cook had offered to help Jobs battle pancreatic cancer by donating part of his liver.
