You've got a drawer full of old cell phones — smart phones, to be exact — yet you're already eyeing a new device. Maybe you should slow down for a moment and consider selling your old gadgets first, because if this chart is to be trusted, you can get a nice chunk of cash for them.
With the help of eBay, the folks at TNW put together this infographic showing just how much some of the most popular smart phones sell for on average. Take a look.
Keep in mind that the data is limited to mobile devices sold through eBay between September 2010 and December 2010. That means that you could easily get more or less for your device at this point — especially if you sell it via a different channel. Nonetheless, you can still get a pretty decent idea of how much to demand when you start cleaning out that gadget drawer of yours.
