Miguel Helft, reporting for the New York Times:.

Mark Papermaster, the Apple executive in charge of hardware for the company’s flagship iPhone, has left the company in the wake of widely reported problems with the antenna of the recently introduced iPhone 4.

It is not clear if Mr. Papermaster was ousted or left on his own accord.

The word on the street is that he was fired. Not surprisingly, senior vice president of Macintosh hardware engineering, Bob Mansfield, will be taking over his responsibilities.
