Now that we’re all convinced our old iPhones are scrap metal, my good friend Shawn Wilkins did a great rundown of the easiest way to sell that relic off. For the record, I did eBay Instant Sale on Shawn’s recommendation and it was a breeze. I got a guaranteed $200 for my wife’s iPhone 4. The best part is you don’t have to ship it until October 1st. Make sure to check out the full list of options. Shawn’s done them all, so he speaks from experience.
