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.
Verizon and Sprint phones are not "locked" the same way as AT&T phones. A CDMA phone, Verizon and Sprint, will only work on one or the other at a time. You have to Flash a CDMA phone to change it from one to the other. Where with a GSM phone that is unlocked, you just swap the SIM. If the hackers do find a way to flash the Sprint to Verizon or vice versa, you still won't be able to use it on AT&T. There are two radios in the phone, one for CDMA and one for GSM, but you can't use them both at the same time.

Edit: let me add that that is the way I understand it.
