True, but the policy can be replaced with a blank policy if the device is not going to be used on the BES again.
Just to clarify: You cannot get around the IT policy while connected to the BES. It's that simple. If you want to disconnect and never reconnect it again, there are fixes. However, it's not possible to get around their policy while connected to their BES.
maybe your IT guys can allow you to use your camera for certain timeslots during the day or for specific days during the week.. if they just can't then there's no other way other than to get another BB and not hook it up with BES
