CNET has reached out to Apple for confirmation and will update. Reporters for CNBC and the Wall Street Journal tweeted that Apple is starting the program, letting customers swap their old phones for credit toward a new one, Friday in the US.
Word of such a service cropped up in June, when Bloomberg reported that Apple was working with Miami-based trade-in company Brightstar on a program that would let consumers bring in their used iPhones for a discount on newer models and potentially for credit on other items in Apple's stores.
Next month's Apple event has the rumor mill churning out speculation at top speed, but the computer maker is generally expected to be introducing a high-end flagship iPhone, called the iPhone 5S, along with a lower-cost option, called the iPhone 5C.
Reports Monday indicated the company was close to firing up a trade-in service for its flagship smartphone. Apple was said to be preparing retail workers, giving first trainers their instructions Monday for them to start teaching other employees, and may have even started piloting the program in some stores.
