“With one iOS device update out of the way for 2012, Apple is working on updates to the iPhone and iPod touch,” Mark Gurman reports for 9to5Mac.

“Much like they did last year, Apple has internally seeded a prototype next-generation iPhone with the iPhone 4 design,” Gurman reports. “The actual next-generation iPhone is specifically said to not include the iPhone 4/4S design, but Apple is testing these new devices in older casings to throw off leaks. The purpose of the prototype iPhone that we heard about is to test a variation of the “A5X” chip in an iPhone.”

Gurman reports, “Like the A5X-powered iPad, these new iPhone prototypes are packing 1GB of RAM… Apple is working on a fifth-generation iPod touch that is labeled iPod 5,1 internally… Perhaps Apple is finally moving to an A5 or A5X-like chip in the iPod touch.
