IPhone Unlocking the Sprint network.?

I want to sell my iPhone to my cousin, but he said he wants me to unlock the Sprint network. Be that the way to escape, but I know nothing about unlocking. So someone does not know how? If so, how I can enable it for Sprint?

I work for the sprint and there is no way to block United Nations Sprint … AT & T and Sprint out the work of two completely differfent networks and the network as far as I know it is not possible a GSM phone (AT & T) to work on a CDMA (Sprint).
