Samsung has sold over 10 million units of the Galaxy S 4 worldwide, and we have one of them in our possession and just waiting to find a home. This particular version is the GT-I9500, which is an unlocked international model that sports the octa-core Exynos chipset, and we have SellCell.com to thank for the opportunity to hand it out to a lucky reader! If you're looking to sell your phone and get something new, the website -- which bills itself as the "number one mobile phone and tablet trade-in price comparison site" -- invites you to come and see how much your phone is worth. So head below and enter via the widget for your chance to grab an octa-core GS4 for yourself!
