If Apple and Samsung were humans rather than multi-billion dollar multinational corporations, the best way to describe them would probably be "frenemies." Time and again one looks to the other for inspiration, money, or as a source of parts, and today's no different. The latest? Reuters reports (sourcing Korea's Electronic Times) that the Korean tech giant is going to launch a phone upgrade program like Cupertino did last fall with the iPhone 6s and 6s Plus. Basically, you'll be able to upgrade every year so long as you're on a contract.
