This is the baseband platform used in the iPhone 4 and iPad 2 (GSM). It is produced by Infineon and is based on the X-Gold 618.
The firmware is based on ThreadX, a realtime OS.
Firmware files are signed for a specific device by Apple during the restore process. As a result, the baseband will allow downgrades provided that Apple is still signing the firmware.
