I would be interested in learning more about this, for my T4i. If it is software, and doesn't modify the firmware, this would imply that it has to be installed on the memory card you are using at the time, yes? If this is true, then would this have to be reinstalled each time you format the card?
Ah! Good question. And no, it doesn't!
It's quite clever, it lives in memory, formats the card and then restores itself, which is fine so long as you trust it!
