If you look at Kevin's example traces on the EDUCAUSE WIRELESS-LAN listserv
you'll see that the ARP packets are in fact unicast.

Iljitsch's point about the fact that iPhones remain on while crossing
wireless switch boundaries is exactly dead on.  If you read the security
advisory you'll see that it involves either L3 roaming or two or more WLCs
that share a common L2 network.  Most wireless clients don't roam in such a
big way.

With the exception of our 1000+ Cisco 7920 phones...

Then again, they probably work just fine with Cisco's other products, heh.
