Apple's displeasure with Samsung is widely known. Apple sees Samsung as a copier of its innovations, a charge Samsung has repeatedly denied. It's surprising the two companies are still on speaking terms. The iPhone maker earlier this year won the initial ruling in its patent infringement claim against Samsung and last year acquired flash memory maker Anobit in what appears to be the groundwork for greater independence from Samsung, a supplier of flash memory. But if there's bad blood between the two companies, they still know how to put their differences aside to do business together. According to UBM TechInsights, Samsung appears to have manufactured the A6 chip for Apple.
