We always say that folks over iFixit are just too quick. The have already got their hands on the Verizon iPhone 4 to reveal many interesting facts. There is only one interesting thing that have found in it. The Verizon iPhone 4 uses a Qualcomm MDM6600 baseband chipset which is not only supporting CDMA but also the high-speed HSPA/ AT&T GSM.

Only the CDMA part is enabled which means you can activate the GSM part to switch between both networks using the Verizon iPhone.

According to the iFixit:

“It may be that it was 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“.

“This is the same chipset as the Droid Pro world phone. It supports both GSM and CDMA-which means that Apple *could* have supported GSM!”

May be it was less complicated for them to use such infrastructure. They could have release single phone to support both networks (AT&T and Verizon) on it. It seems that iPhone 5 will also have a similar structure or may be Apple has something interesting to reveal which we cannot predict right now.
