As expected, the first teardown carried out on the Verizon iPhone 4 showed that the smartphone was equipped with a Qualcomm chip, the MDM6600 to be precise.
The component is both GSM and CDMA compatible (supports HSPA+ data rates of up to 14.4 Mbps and CDMA2000 1xEV-DO Rev. A/Rev. B) but in the case of the Verizon handset, only the CDMA features are used.
This prompted 9to5mac, which carried out the teardown with iPhone repair specialists to say that iFixyouri, it all but guarantees that the iPhone 5 will be a dual mode phone capable of working everywhere except in China.
It also opens the prospect of having the same chip used in the iPad 2 as well and, perhaps in the next iteration, a full integration of with the Apple A5 or A6 SoC.
This will reduce production costs, slash power consumption and heat dissipation and free some space on the phone's motherboard.
As a side note, Verizon still doesn't run CDMA2000 1xEV-DO Rev.B, doing so would allow it to offer data transfer speeds of up to 9.3Mbps and simultaneous voice and data.
iFixit also notes that it might be "easier to design antennas for a CDMA-only phone—this phone supports two cellular frequency bands, while Apple supports five bands in the GSM version."
