This is the device in the iPhone that manages all the functions which require an antenna. The baseband processor has its own RAM and firmware in NOR flash, separate from the ARM core resources. The baseband is a resource to the OS. The Wi-Fi and bluetooth are managed by the main CPU, although the baseband stores their MAC addresses in it's NVRAM.
The iPhone's baseband processor is the S-Gold 2 and the iPhone 3G makes use of the X-Gold 608 chip for this purpose.
