So this notion, in the trade press, that a separate iPhone needs to
be produced "for CDMA systems" is simply wrong. Ever since the 3G
iPhone came out, Apple has supported CDMA. To support other CDMA
systems, the difference is WAY LESS than what Apple had to swallow
going from their 2.5G to their 3G GSM iPhone variants!
Sorry, but existing iPhone do not support CDMA.
It may well be true that the differences in 3G networks are smaller
in the 3G world, but the chips in existing iPhones do not support
Verizon or China Telecom networks. There is also an issue with
Verizon's network in that it cannot simultaneously support voice and
data, a very important feature for the iPhone. In order for the
companies to offer a Verizon iPhone, BOTh will need to implement
changes to the devices and networks.

Verizon to Support Simultaneous Voice and Data Transmission? - Mac Rumors
Wednesday May 19, 2010 12:32 PM EST; Category: iPhone
Written by Eric Slivka
Boy Genius Report briefly notes that it has received a tip that
Verizon may be preparing to roll out network technology that would
enable simultaneous transmission of voice and data, a feature that
both Apple and AT&T have trumpeted on the iPhone.
We have been told that when the mythical Verizon iPhone materializes,
assuming it's not a LTE unit, it might launch with VoRA; Voice over
Rev. A. According to our source, Verizon has been testing VoRA as a
precursor to VoLTE, and as long as the network upgrade timeline and
iPhone release are aligned, we should see this happen.
Implementations of the CDMA2000 standard currently used by many
carriers around the world, including Verizon, do not support
simultaneous voice and data, a drawback viewed by many as significant
in comparison to the UMTS standard employed by AT&T and all other
current iPhone carriers.
