Apple Inc.’s flashy new iPhones may be jamming parts of the wireless network at Duke University, where technology officials worked with the company Wednesday to fix problems before classes begin next month.

Bill Cannon, a Duke technology spokesman, said an analysis of traffic found that iPhones flooded parts of the campus’ wireless network with access requests, freezing parts of the system for 10 minutes at a time.

A single iPhone was powerful enough to cause the problem, and there are 100 to 150 of them registered on the network, Cannon said. Network administrators have noticed the problem nine times in the past week.

Google Inc. is shortening the life span of its “cookie” data-tracking file - but it’s not clear whether the move would do much to enhance privacy.

Under the new policy, the cookies would expire automatically after two years, instead of in 2038 as is currently the case. However, the two-year period could get automatically extended when users revisit Google’s search engine, so one might have to avoid Google for a full two years to see the cookie automatically expire.
