Apple Preps iPhone Trade-In ProgramSo that iPhone trade-in program Apple was supposed to launch in June but didn’t? It’s finally in the offing. Sources familiar with the initiative tell 9to5Mac and MacRumors that Apple has begun sharing with retail employees the details of a new program that will allow Apple Store customers to trade in their used iPhones for credit toward a new one. And AllThingsD has confirmed independently that this is indeed the case. The program is currently scheduled to go live in September, sources said, though there’s a lack of clarity around the final launch date. It seems likely, then, to expect it to debut alongside the street date of the new iPhones that Apple is expected to show off at its upcoming, and as of yet unannounced, September 10 special event, though I do not yet have hard confirmation of that. As I’ve noted before, Apple CEO Tim Cook is eager to increase the number of iPhone sales made through the company’s own stores. An iPhone trade-in program is a smart way of doing that, driving more sales from upgrade-ineligible consumers looking to buy the latest iPhone and increasing foot traffic to Apple Stores in the process. Question is, will Apple Stores have the sales capacity to handle it all? Apple did not respond to a request for comment on its iPhone trade-in program.
