Just to verify, FBI installs the CIA to the SD card? So if we had a 2.5GB cia, and a 4GB, it wouldn't work because it would need at least 8GB to cover the install? So SD card needs to have 2x the free space of whatever you want to install?
Yeah. It's a bad idea to have a 4GB SD card if you want to use CIA's and CFW anyways.
