Apple CEO Steve Jobs will be a speaker at June's D: All Things Digital conference run by the Wall Street Journal.

The show takes place June 6-8 in California. Its format consists of a series of unscripted Wall Street Journal interviews, live on stage, with the "leaders of the digital revolution".

The Apple CEO showed up last year to demonstrate the iTunes Music Store. This year's speakers also include Microsoft's Bill Gates and HP CEO Carly Fiorina.

Wall Street Journal journalists Walt Mossberg and Kara Swisher last year spoke with: "Microsoft's Bill Gates pondering the future of innovation; America Online's Steve Case giving his side of the failed AOL Time Warner merger; and a lively debate over copyright issues, including a testy exchange between the Motion Picture Association's Jack Valenti and RealNetworks Rob Glaser."
