Can fixing and selling used iPhone 3GS be profitable?
Hi, is fixing and selling used iPhone 3GS phones be profitable? They surely aren't rare but I feel like in a couple years they could reach a certain point where people just want to go back and have one as a collectible. Could fixing minor problems like display, buttons or the back and selling it with all the original intents/ packaging be a profitable idea? Thanks
