This is the baseband processor used in the iPhone 3G, iPhone 3GS and iPad (3G version). It is upgraded with BBUpdaterExtreme. It is also known as the PMB8878 and is also used on the LG KM900 ARENA.

Datasheet

Anyone got one? Infineon provides this, which isn't really useful.

The firmware is a version of Nucleos OS, a realtime OS for embedded platforms. The parser for the AT commands is generated from GNU bison.

Secpack 2.0

This is the security region in the files sent to the X-Gold 608. This is the first 0xCF8 is new fls and eep files.

Layout

0x634--Memory Map
0x714--Descriptor
0xCD4--Post secpack pointer to name
0xCEC--Data length

Endpack

The fls and eep files also have a footer tacked onto the end containing the loader and signature.

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(kAppleBasebandConnectMethodResetModem)
result = IOConnectCallScalarMethod(conn, 1, 0, 0, 0, 0);	//power set(kAppleBasebandConnectMethodRadioOn)
result = IOConnectCallScalarMethod(conn, 2, ?, 0, 0, 0);	//configuring mux
result = IOConnectCallScalarMethod(conn, 7, 0, 0, 0, 0);	//powercycle
result = IOConnectCallScalarMethod(conn, 8, 0, 0, 0, 0);	//preupdate reset
result = IOConnectCallScalarMethod(conn, 9, 0, 0, 0, 0);	//kAppleBasebandConnectMethodNotifyBasebandPoweringDown
