This is the baseband processor used in the iPhone 3G. It is upgraded with BBUpdaterExtreme. It is also known as the PMB8878
Datasheet
Anyone got one? Infineon provides this, which isn't really useful.

Known Firmware Versions

Accessing Interactive Mode
Interactive mode isn't accessed by sending characters to the baseband. Instead a GPIO pin is raised with a kernel call to preupdate reset.
result = IOConnectCallScalarMethod(conn, 0, 0, 0, 0, 0); //reset result = IOConnectCallScalarMethod(conn, 1, 0, 0, 0, 0); //power set result = IOConnectCallScalarMethod(conn, 2, 0, 0, 0, 0); //configuring mux result = IOConnectCallScalarMethod(conn, 7, 0, 0, 0, 0); //powercycle result = IOConnectCallScalarMethod(conn, 8, 0, 0, 0, 0); //preupdate reset
