Someone else asked and the posted replied it was a QCOM chip. But these parts are not referenced in the teardown.
GPS function is integrated in the RF&Baseband chip MDM6600,WiFi/BT is modified to a murata MCM module,which probably based on BCM4329 too.
Well excuse me if I’m not an expert on part numbers! I did a find and looked for GPS, wi-fi, and neither came up. In the ATT iPhone 4 review, it did. It also didn’t call out the Broadcom part numbers which it did for every other part. You don’t need to be so rude about it.
If you’d actually bothered to take two seconds to use CMND+F on the teardown, you’d see it IS referenced, and you’re told to look at the GSM teardown, which points you here for the Wi-Fi chip and here for the GPS chip. They use the same frequencies for both.
