Grant “chpwn” Paul on how to disable Carrier IQ on iOS:
>However, it does appears to be disabled along with diagnostics enabled on iOS 5; older versions may send back information in more cases. Because of that, if you want to disable Carrier IQ on your iOS 5 device, turning off “Diagnostics and Usage” in Settings appears to be enough.

This is going to get a lot more interesting.
