Apple boss agrees to biog

After years of maintaining a closed book on his private life to unauthorised chroniclers, Steve Jobs, the Apple boss, has finally agreed to participate in an official biography about his life.

The technology pioneer has chosen Walter Isaacson, who has published bestsellers about Benjamin Franklin and Albert Einstein, to be his official biographer.

Publishers Simon & Schuster announced that iSteve: The Book of Jobs will be published in early 2012.
