I'm already written about this too many times, so i'll keep it short.
It would be an understatement to say that I am disappointed that Apple doesn't *already* have a CDMA iPhone. There is NO legitimate argument for not creating one (or using a dual-CDMA/HSPA chipset in the single model iPhone) as there are ~100 million CDMA customers in the United States --- easily the largest potential market for the iPhone so far based upon total cellphone users and the iPhone's extensive popularity among the public. Beyond that, there are ~400 million CDMA subscribers in the world, and in the future carriers like Verizon who are moving to LTE will continue to run their CDMA network and possibly have dual-use LTE/CDMA devices for the 1-2+ years required to build-out their new network to the footprint of the existing one.
Although we don't know the details, this enormous potential market obviously overshadows any benefits from maintaining exclusivity with AT&T. It may have been necessary initially to enter the market, but now it is just a big ball and chain. Even if opening the iPhone to the Verizon and Sprint led to a reduced average subsidy, the potential doubling or more of unit sales would easily more than make up for the lower revenue per phone.
As an Apple enthusiast, device owner, stockholder, and especially as a fledgling software developer, I will be very upset if Apple continues this nonsense exclusivity.
