Have you ever wondered how much Apple's latest smartphone iPhone 4S costs? An iPhone 4S teardown analysis from iSuppli reveals the answer. The 16 GB model iPhone 4S carries a bill of materials (BOM) of $188, while the 32GB and 64GB version's BOM are $207 and $245 respectively.

Adding in $8 manufacturing cost, the total costs of 16GB, 32 GB and 64GB version are $196, $215 and $253. The difference in the prices was because of the different capacity of NAND Flash memory in the three iPhone 4S models. Each 16GB of storage costs $19.20, according to iSuppli.
Apple's latest smartphone iPhone 4S, which features Siri, A5 processor and 8-MP camera, comes in 16GB, 32GB and 64GB, priced at $199, $299 and $399 with a two-year contract, respectively.

Key among these changes is a custom part from Avago that helps give the iPhone 4S its unique capability to be used in multiple wireless systems globally, while still keeping costs down. said Andrew Rassweiler, senior director, teardown services, for HIS.

In another surprise development, the 4S employs a Hynix NAND flash memory device. While IHS has already confirmed multiple suppliers for this part, it does mark the first time that IHS has identified a Hynix NAND flash in an iPhone, as opposed to devices from Samsung Electronics Co. Ltd. or Toshiba Corp. seen in all previous iPhone and iPad teardowns, Rassweiler added.

The A5 processor costs $15, while the cameras cost $17.6. The iPhone 4S' Retina Display goes for $23, and the touch screen costs $14. The costs of each part are listed in following sheet.

The iPhone 4S maintains many of the same design elements and components as the iPhone 4 models, which disappointed many Apple fans.

However, when iPhone 4S hit stores on Oct. 14, it smashed previous debut weekend sales record. Apple sold 4 million units of iPhone 4S in the first three days of launch compared to 1.7 million units of iPhone 4 sold in its debut weekend in 2010.
