A new cost breakdown by IHS iSuppli has given more definitive raw parts costs for the iPhone 4S. A 16GB version of the phone is estimated to cost about $188, or within 50 cents of last year's model when it was new. The switch from an Infineon (now part of Intel) chip to the dual-mode Qualcomm chip had little impact on the cellular chipset, which in total cost about $14 to $15.
