That is a nice idea, in fact I am also doing that thing, seeling some old stuff online. I sell old smartphone, laptop, and other mobile accessories. Most I have for sale are used iPhone 4 cases that I have them bought from Keka Store. Since I have the iPhone 5s today, the iPhone 4 covers and cases as well as the device are up for sale, need to get into mobile evolution. Now, most of my cases for iPhone 5 are personalize and customize with my own artwork using the idea from http://www.kekacase.com/design-your-own/ipad-cases.html , you too can try it.
