I manage multiple iPhones at my organization using Active Sync settings in Exchange 2007 as well as the iPhone Configuration Utility. I've recently performed tests where I concluded that if I were to obtain a user's phone (ie they lost it), I would be able to access much of the information on the phone without their password by jailbreaking it to gain root access and retrieving .db files from the phone.
I'm looking for a mechanism for detecting a phone has been jailbroken and automatically wiping or notifying us when it occurrs. Note that this is for AFTER we've alreay pushed the configuration profile to the phone, NOT during initial configuration.
