Speed increases are an expected part of Apple’s iOS device hardware upgrades, but what Apple has up their sleeves for speed enhancements is typically up for debate. The first-generation iPad clocked around 1GHz with the single core A4 processor, and —a year later—Apple bumped the iPad’s chip to dual-core-speed with the A5 processor. While not quite confirming that a quad-core processor will power Apple’s third-generation iPad, we have obtained evidence that suggests Apple is currently working on quad-core iOS devices.

The references to quad-core iPhone and iPad chips come by way of a hidden panel that describes cores that are supported by iOS device hardware. The updated core management software includes an option of “/cores/core.3,” and this represents a fourth available processing core… more details after the break:
