This is the device in the iPhone and iPad 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 its NVRAM.

The iPhone's baseband processor is the S-Gold 2. The iPhone 3G, the iPhone 3GS and the iPad make use of the X-Gold 608 chip for this purpose. The iPhone 4 (GSM) and iPad 2 (GSM) use the XMM 6180, while the iPhone 4 (CDMA) uses the MDM6600 and the iPhone 4S uses the MDM6610

Seczone

This is the area in the baseband where the lock state is stored.

Encryption

Many of the sections are encrypted using TEA based off the CHIPID and NORID. See NCK Brute Force for more info.
