Apple's next-generation iPhone sports chips from Samsung Electronics, Micron Technology and STMicroelectronics, according to a disassembly analysis by technology firm iFixit.
Samsung and Micron supplied flash memory and STMicro provided accelerometer and gyroscope chips used for orienting the new iPhone, iFixit claims.
Broadcom supplied the GPS receiver and the low power 802.11a/b/g/n with Bluetooth, while Texas Instruments offered the touch screen controller
Other suppliers included Apple mainstay Cirrus Logic ( (audio codec, Apple branded), OmniVision (CMOC censor 5mpx camera) and Skyworks Solutions (GSM/GRPS Module)
The iPhone 4 is also powered by the 1 GHz ARM CORTEX A8 core as that found in the Apple iPad as well as the Samsung Wave S8500UBM smartphone, according to a recent analysis by UBM TechInsights
Apple doesn't disclose who makes the components that go into its smartphones.
The new iphone 4 begins selling in the U.S., Japan, France, Germany and Britain this week but will be in 88 countries by September. Apple moved 600,000 of the slimmer $199 iPhone 4 last week in its first day of pre-sales, a deluge of interest that jammed ordering systems and squeezed carrier partner AT&T's inventory.
