I think that Apple is not going to make a CDMA phone until they can include LTE with it. That would put it next year for the Verizon introduction. It will be interesting to see if they make a all in one Phone with GSM/hspda/CDMA/EVDO/LTE.
Also with the overload of AT&T and Verizon system the new IPhone should add the 700mhz and 1700mhz/2100mhz bands to get more bandwidth. I see AT&T and Verizon adding both bands to the towers when they upgrade to LTE.
