producing a dual band phone is not beyond Apple's desire to make money from suckers..... I mean customers of their devices.
Don't put Apple's desire to make even more money off their cash cow into a box. Not saying there will be a CDMA phone, or it will be on Verizon, just that it's not anything but timing for Apple right now.
Well, it is possible for Apple to later on make a UTMS/EV-DO/LTE phone if Apple feels it's worth it, but I don't see support for AWS ever occurring unless the antenna manufacturers start making quad-band UTMS radios or if Apple decided that it's worth it to demand such a radio to accommodate a rather small carrier.
But I still don't think it's likely, especially considering the timing of the imminent LTE roll-out. If even Verizon deems it unlikely....
