I'm not sure we're at quite the level of modularity that would allow that yet. For example in a smart phone, RF design is a big issue (antennae efficiency / avoiding interference), which may preclude making the baseband component swappable (which is one component we still seem to be iterating). There's also the issue of designing a compact form factor that wouldn't result in huge space inefficiencies within the phone. Maybe in another 10 years
