I've been predicting this for almost a year now. My bet is that we'll see one iPhone model which does GSM and CDMA, and isn't tied to any contracts. You'll be able to buy one phone, use it wherever you like, and it'll be unlocked so you can easily carry it with you and use local SIMs worldwide. When this happens, I'll buy a new iPhone. Until then, I still have my 1st gen, jailbroken, iPhone and it works just fine as pay-as-you-go, thanks. :)
