The main instruction set of the baseband. You can get these files from /usr/local/standalone/firmware on the corresponding firmware's restore ramdisk or from an IPSW under /Firmware.
The baseband version that comes with each iPhone firmware is listed on the firmware page and also on the X-Gold 608 article for the iPhone 3G/iPhone 3GS.
Baseband firmware files have been codenamed Trek, ICE, and MAV.
File Structure
The .bbfw file format is a ZIP archive containing Info.plist, Options.plist, and multiple firmware files. In the past, these were EEP and FLS files, the external EEPROM and firmware, respectively. In modern iOS versions, these are .mbn files.
For example, the iPhone 4 has a single baseband firmware file. The 4.0 baseband firmware filename is ICE3_01.59.00_BOOT_02.06.Release.bbfw and contains contains four baseband firmware files.
