I wonder what other unintended consequences we'll see coming out of iphone-mania.

the network administrators at Duke University, are reporting temporarily knocking out anywhere from a dozen to 30 wireless access points at a time.

apparently it’s due to misbehaving iPhones flooding the access points with up to 18,000 address requests per second, nearly 10Mbps of bandwidth, and monopolizing the AP’s airtime.

This has become a big story today:

"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."
