Process
iTunes side
iTunes has pretty much no say in how the restore goes along. It will send the DeviceTree, RAMDisk, and Kernel (respectively, as far as I know), but in firmwares 1.1.1 and up the program on the RAMDisk pretty much runs the show. On the Restore RAMDisk, it is called 'restored_external'. On the Update RAMDisk, it is called 'restored_update'.
