iFixit tore down the Verizon iPhone 4 and fond out inside a Qualcomm MDM6600 chip that supports HSPA+ data rates of up to 14.4 Mbps, as well as CDMA2000 1xEV-DO Rev. A/Rev. B. The same chipset has the Droid Pro that supports both GSM and CDMA - which means that Apple could support GSM! Apple of course has not included a SIM-card slot in the Verizon iPhone, and thus the device can not actually be used on GSM networks. The use of this particular chip signifies that the iPhone 5 will surely be dual-mode, allowing Apple to ship one handset for both Verizon and AT&T, as well as every other carrier in every other country.
