Did forensic analysis on my iPhone during Airplane Mode isolation. Kernel stats show 2,657 packets transmitted and 84.5MB processed through mDNSResponder while interfaces report "inactive". Found a parallel utun2 tunnel bound to IDS framework that persists during isolation. Applied Shannon-Hartley theorem to verify the channel capacity supports this volume. Either I'm misunderstanding legitimate system behavior, or this is a covert channel. Reproducible steps and raw evidence included.
