It's entirely possible that there will only be one model of iPhone 6 that will work all around the world on every supported carrier (in your choice of color, of course). Is anybody else pursuing this as well?

normally qualcomm requires a customer to buy their CPU and radio chips for a phone. since the US is way ahead in LTE and we also have CDMA here, samsung has to buy qualcomm LTE chips and CPU's for their US phones.
apple somehow struck a deal with qualcomm where they only buy their radio chips and get support in pairing them with their own CPU's
