I read an article on the Internet that KT(Olleh) and SKT shops started to sell second hand cell phones, but I am not sure they are still selling them. I think you could walk in any KT  or SKT shops for the availability. If you cannot find one, you could go to WWW.Auction.co.kr to buy one online. If you have any problems please send me a message, I might help you out.
