Hi Peter,

How is your wireless network designed?  Might be able to suggest a  
small architecture change for a quick mitigation.

In our network we configure iPhone/Touch profiles to hand out to  
Faculty and Staff and Students that allow them to connect to our  
network via 802.1x.  Works great, the students really have adopted  
using the profile.
