Much like tubehax, ironhax requires that your console be on a firmware version between 9.0 and 10.3, and that you have IronFall (previously available for free on the eShop) installed on it.
Unlike tubehax and ninjhax however, IronFall is not "self-sufficient" : you will need either tubehax or ninjhax to perform the initial ironhax install.
The advantage of ironhax is that unlike tubehax, it only requires an internet connection the first time; after that, you'll be free to use it untethered !
