In some yes, in some no... it depend on how the smartphone was designed: On one end some smartphones (openmoko GTA02,golden delicious GTA04), the baseband is isolated(tough on GTA04 it has access to a GPS with no antenna(so it can't work)) . And on the other end there are smartphones with qualcomm System on a chip...where the modem and the CPU are in a single chip: The modem part has the audio DSP connected to it, the GPS. And the baseband uses shared RAM memory and shared NAND(if I remember well)... And I'm not sure but maybe the baseband is even needed for booting the main CPU... There are also systems in between like the galaxy S/Neuxs S that uses shared memory but do not have other problems... Denis.
