There is only one version of the 4S so it will have a SIM card holder, and if it's an att phone, it will have a SIM card.
So Sprint and Verizon users could, with an unlocked phone, use the CDMA side here, and then buy a SIM card when traveling abroad using the GSM radio in the phone.
Actually, I don't think that is how they said it would work. I think they said that if you have a Verizon or Sprint phone, you will be able to roam with their "world" partners. To me this means that you will have to pay Verizon or Sprint to roam internationally, just like you do with AT&T.
The only unlocked version is the AT&t version, and you can just insert a foreign or TMobile SIM into those and use wherever you wish.
The carriers are still locking these down as much as they can.
But there has never been an iPhone that was not eventually unlocked. It would seem that for example an unlocked AT&T world iPhone 4S would work on Sprint, Verizon, and with a SIM card on TMobile.
