Apple is currently using Samsung manufactured Cortex-A8 processor for the iPhone 3GS. Even the original (iPhone 2G) and iPhone 3G were using a Samsung 32-bit RISC ARM processor. But a Korean newspaper reported that this may not be the case for the upcoming iPhone, better known as the iPhone HD. It seems Cupertino may be using its own variation of the new A4 processor for the new device. And this is certainly a bad news for Samsung.
