Well, good, if the radio and baseband do not live on-die with the AP. Market forces are pushing for a completely integrated design, but it's interesting from a security perspective.

The baseband is still considered the master CPU during boot - at least on the CDMA Nexus. So although there are some corner cases in terms of architecture, the security model is still completely broken. Send a payload to the baseband over the air, compromise it, and the entire phone is yours.
