CSR CEO John Scarisbrick says the launch of the iPhone is not only important to Apple but also to its suppliers.

Although CSR, like all Apple suppliers, cannot confirm its inclusion in the iPhone, teardowns from the likes of iSuppli confirm CSR’s inclusion on the bill of materials.

“The iPhone is more important than just another mobile phone, for its suppliers as well as for Apple,” Scarisbrick told EW.

This is significant coming from Scarisbrick who claimed that CSR has its Bluetooth chipset in eight out of the top 10 mainstream mobile phones.

CSR appears in the teardowns of the iPhone with its Bluetooth chipset. Other semiconductor suppliers for the iPhone include Infineon Technologies, Micron Technology, Samsung and Wolfson Microelectronics.

The iPhone was launched last week in the US where it will operate exclusively on AT&T's wireless network. It will be available in a 4Gbyte model costing $499 or an 8Gbyte model costing $599.

According to iSuppli's teardown, the 8Gbyte version of the iPhone has a total hardware bill of materials and manufacturing cost of $265.83.

The European launch is expected later this year.
