It's on all iPhones on all carriers running all versions. However, it is not the same version, and this version of CarrierIQ covers far, far less. It is not keystroke logging, not watching web activity, not watching texts. This version also ONLY RUNS when the iPhone is in diagnostic mode. It is set to never run while the phone is operating normally.
