Will Sprint's iPhone 4S work with any SIM after unlocking?
I am thinking about pre-ordering my iPhone from Sprint, as I already have an account with them and can add another phone.
I travel back and forth to different countries that use the GSM network. If I unlock the phone, will it accept the other countries' native carrier sim card?

No one really knows yet because there is not a jailbreak (or in that, details about a jailbroken unlock) to really know for sure. After the 4S hits the streets with iOS 5, and the crackers get ahold of it, i have no doubt you'll eventually be able to use it on any network with a JB'ed unlock, but who knows how long it'll take for that to happen...go back and read about the iPhone 4 and iOS 4 to see how it went after that was released...

When I placed my order for the Verizon version (also CDMA), I was asked if I wanted the phone unlocked for international use. If I said "yes", I would have to sign up for one of their global plans. I will eventually jailbreak the phone for mobile hotspot access and to unlock.

Apples website says the unlocked Iphone4S's won't be released til November. To me that means these phones are still locked to which carrier but can be unlocked by jailbreak and than used with Sprint,AT&T or Verizon. Even can be used on at&t go phone plan as long as you get a sim card cutter but thats another topic.

On the Apple 4S video, about 2:25 in, they say all are world phones and both GSM & CDMA can roam GSM worldwide. On the Apple website, it says this:
Cellular and Wireless
UMTS/HSDPA/HSUPA (850, 900, 1900, 2100 MHz);
GSM/EDGE (850, 900, 1800, 1900 MHz)
CDMA EV-DO Rev. A (800, 1900 MHz)4
802.11b/g/n Wi-Fi (802.11n 2.4GHz only)
Bluetooth 4.0 wireless technology

The unlocked phone you all are reading about is a GSM only phone. In other words, the AT&T phone.
The CDMA phones (at least Verizon for sure) will NOT be unlocked, but they WILL have global capability. You will be forced to use the SIM card Verizon provides and pay through the nose for data. So you can use the GSM radio in the Verizon iPhone but it is locked to Verizon's SIM card. You can't buy an inexpensive SIM card from the country you are traveling in and use it.
So yes, the iPhone on Verizon and Sprint is global, but you are locked to paying their extremely high fees for the access.

Remember world phone does not mean you get to put a SIM in it from any network in the world, only that it will roam on GSM networks as a CDMA phone... Buy unlocked, but if you are subscribed to a CDMA carrier, you may be forced to use their GSM SIM as well - from a partner if not their own network.

People are misunderstanding the difference between a world phone. A unlocked phone and a world phone thats locked, etc.
1. at&t phone locked to at&t
2. sprint phone locked to sprint
3. verizon phone locked to verizon
4. Phones are capable of using other networks in world phone use, like what Timhewitt said. You have a locked at&t phone you travel to russia or something, you can roam over to a cdma network.
Than there other unlocked Iphone4S being release in October that I'm assuming you can do whatever with.
To add since these phones are GSM/CDMA they can be jailbroken and than unlocked and capable of being used on any carrier.

In essence, you'll be required to use Sprint's international roaming options.

The real answer is this...
If the carrier will unlock the phone for you yes you can use any sim... or later on when a jailbreak comes out you can do that..
Apple does allow carriers to unlock phones but its up to the carrier not apple..
and as far as having a sim go's any phone with a gsm radio has a sim slot

Woohoo, the first post on the TiPb main page answers this question... what what I wanted to hear!! Yes it is unlocked so you can use a local sim card when traveling out of the country. Sprint will offer this out of the box and VZW you have to request it 60 days in advance. Sorry AT&T users, according to this you will have to pay roaming charges through them

This is why its confusing. The Iphone4S that is coming out in October 14th will be a true WorldPhone, GSM/CDMA but is locked to each carrier. But for some reason Apple is selling in November unlocked Iphone4S's. Which is confusing, why not have all unlocked. No one is for sure if its gonna be as easy as switching a sim car or what on these phones released on the 14th.

I think there is still some confusion about this: Sprint won't sell iPhone 4S with unlocked micro-SIM card slot
Gruber will test it this weekend: Daring Fireball Linked List: Drama on the Sprint International Unlocking Front
