Samsung is still the main producer for Apple's next-generation mobile processor, the A6, claims an anonymous executive with a South Korea-based Apple supplier. "Apple has been in talks with Samsung over shipment of its A6 quad-core mobile processor (AP) chips to be used in the next iPhone. It appears that Apple clearly has concluded that Samsung remains a critical business partner," the person tells the Korea Times. Samsung is in fact said to be boosting output of A6 chips at a manufacturing plant in Austin, Texas.
