Jobs and Woz: Together Again?
Steve Jobs, chief executive of Apple, and his former partner, Steve Wozniak, are said to be developing a "smart" phone in an attempt to kick-start the market for next-generation mobile phones in the same way that the company's computers popularised personal computing.
Wozniak has been involved with Danger.com since late last year. Danger is due to release its combo cell-phone and web-browsing handheld ("Hiptop") in the fall.
