Our friends iFixit dissected as usual the first device in their hands. Here are the results of their investigations.
The location chipsets of the iPhone 4
We find in the iPhone 4 same components Broadcom in iPad, namely :
- The module BCM4329 802.11n/Bluetooth 2.1+EDR and FM receiver combo
- The Broadcom A-GPS chipset BCM4750, once again prefered to Infineon competing chipset.
In addition, we find out :
- A new gyroscope 3 ST-Micro STM33DH axes
- A new magnetic sensor AKM8975
A particularly ingenious reception system
The stainless steel frame supporting the antennas (Source iFixit)Apple's stroke of genius is to have thought, and succeeded, to integrate GSM antennas, UMTS, GPS, WiFi and Bluetooth inside the stainless steel frame of the device ! This should significantly fix reception issues encountered with previous devices.
It only remains to wait for boatmen feedback soon equipped with the new smartphone. But there is no doubt that they will be positive.

iPhone built-in GPS : some details
I just received my iPhone 4 and GPS ( as for the rest), it's night and day compared to my 3G.
He is very quick to position himself, It is very accurate and much more sensitive. I pick up the GPS signal even indoors (in the attic anyway…) or in the glove compartment of my car. I had to put my 3G under the windshield in the ventilation grilles to get the same result. I think the new BCM4750 chip and the large antenna in the case have something to do with it.
