all the inner armor files, including a bunch that arnt avail in the cash shop yet are in your game folder already. They are the "HFS" files, just like every other item in the game.
I have no idea how to tell which HFS file corresponds to what item though. Some guys at gamevixenzone have the whole thing cracked open but they are only sharing their files and info with ppl who donate to that site. The bastards.
