Apple’s online store has begun selling refurbished iPhone 6s models, allowing customers to save money on last year’s iPhone models by purchasing certified refurbished versions. A variety of colors and capacities are available, with prices starting at $449 for a 16GB iPhone 6s — about $100 less expensive than a brand new entry-level iPhone 6s, although it’s worth keeping in mind that Apple has doubled storage capacities on this year’s iPhone 6s and iPhone 6s Plus models, making the refurbished iPhones arguably less of a deal — a brand new 32GB iPhone 6s sells for $549. All refurbished iPhone models currently being sold appear to be unlocked and SIM-free, meaning they can be used on any carrier.
