Those who plan to upgrade to a shiny new iPhone next month (a gold one, perhaps?) now have a new option from Apple: They can bring their old iPhone to an Apple store and trade it in for credit toward a new one, reports CNBC. Savvy shoppers can easily find better trade-in deals elsewhere, but 9to5mac says Apple apparently figures that the convenience of walking into a store with an old phone and walking out with a new one will trump that. The program applies to all generations of the iPhone, and Wired has the details of how it works for consumers. (More Apple stories.)
