Apple is purportedly testing a next-generation hardware platform for the next iPhone revision expected later this year. While the external design is still being worked out, test mules using an iPhone 4S body with an A5X "variant" are reportedly being circulated internally at Apple for testing, according to sources speaking to 9to5 Mac. Furthermore, it appears that the next-generation iPod touch could be in store for a much-needed hardware upgrade.
First, these sources claim that Apple is testing next-generation iPhone hardware, which will utilize what the site characterized as a "variation" of the A5X processor used in the third-generation iPad. Externally, these test devices are cosmetically identical to an iPhone 4S "to throw off leaks," but the next-gen hardware is still expected to have a revised form factor.
