Everybody else is doing it, why not Apple? More high-end smartphones, including the Samsung Galaxy S III and the global version of the HTC One X, are packing a powerful quad-core processor. The next iPhone will too, reports say. Apple's long-awaited A6 CPU is the odds-on favorite. Indeed, iPhone fans wouldn't be happy if the new model featured the A5X, a dual-core chip with quad-core graphics that powers the third-gen iPad.
