Three things you need to know about l'affaire iPhone (http://www.pbs.org/wnet/need-to-know/files/2010/05/karronculture-badge.gif)When the technology website Gizmodo (http://gizmodo.com/) paid $5,000 for a secret prototype of Apple's next-generation iPhone, it attracted the interest of California prosecutors. But the authorities' response may also be tainting Apple's image — in part because the company has a representative on the board of the law-enforcement task force (http://www.reacttf.org/) that's pursuing the case. Need to Know cultural correspondent Rick Karr considers the bigger picture: First, he talks ethics with Bill Grueskin (http://www.journalism.columbia.edu/cs/ContentServer/jrn/1165270051276/JRN_Profile_C/1212609902145/JRNFacultyDetail.htm) of Columbia University's Graduate School of Journalism. Second, he chats with Lucy Dalglish of the Reporters Committee for Freedom of the Press (http://www.rcfp.org/) to compare the raid on the Gizmodo blogger's home with federal prosecutors' efforts to get Pulitzer prizewinning New York Times reporter and author James Risen to give up his sources (http://www.pbs.org/moyers/journal/02292008/profile4.html). Finally, Rick talks with David Carr about his recent New York Times column (http://www.nytimes.com/2010/05/03/business/media/03carr.html), which explored Apple's image in the wake of the incident.
