Why create a CDMA version when Verizon, AT&T, and T-Mobile are all going to LTE (next gen GSM 4G technology)? Apple would also have to bend considerable to be on Verizon before they would be accepted by them. Two major things are having a removable battey, and allowing Verizon Techs to troubleshoot their phones instead of relying on Applestores, pretty much what kept them from getting on Verizon the last time.
I am not sure I'de even get one now even if they were to switch. One they can't be customized like my Windows Mobile phone (Not without warranty issues), I don't want to be forced into buying apps only at their store or stuff that is approved by them. I just like the iPhone because I wouldn't have to have an mp3 player as well.
