i can confirm this directly. a ride into Vegas for DC 20 demonstrated that Alexander's toys have the ability to inject into receive only (airplane mode) and tip to exploitation. (baseband exploits being exceptional at leaking keys, elevating privs, and erasing tracks...) battery out or faraday caged the only effective options.
