ZDNet reports that the iPhone 3.0 firmware will support quad-core processors in an upcoming iPhone hardware revision. Imagination Technologies is announcing a multi-core GPU that could be suitable for iPhone use. Apple, an investor in Imagination Technologies, presently uses a less powerful version of their PowerVR GPU in the iPhone and iPod touch. The likely candidate for the new iPhone's CPU, however, is a derivative of the ARM Cortex A9 multi-core processor.
