As noted widely in the press and in an earlier post here, the most valuable parts in the iPhone 4 were made by Korean companies. Now, as reported in the Donga Ilbo, that pattern is continuing with the iPhone 4S. As reported in a teardown analysis by iSuppli, the phone's NAND flash memory is manufactured by Hynix, while the application processor, the brain of smartphones, is Samsung`s dual-core A5 processor. iSuppli said "die mark" on the product show that Samsung manufactured it. Though the A5 chip does not have the Samsung logo, it holds Samsung`s pattern on its surface as discerned by experts. Before the release of the iPhone 4S, foreign media said Apple changed its main supplier for the A5 chip to the Taiwanese chip manufacturer TSMC. TSMC, however, was unable to meet Apple’s demand in quality and quantity, experts said.
