iPhone 4s CDMA World Phones - How do they work?

Does anyone have one? Have you traveled internationally? When its switches to GSM does it switch to any GSM network like any GSM phone would? If you have experienced this, do you know how much the roaming charges are and have you seen them on your account online? Or do you have to buy a pay-as-you-go SIM from a provider and if you do this do you still get your data or do you just get voice?

I ask because I am looking to get the AT&T version for three reasons: the off chance I do travel, I want my data, I want voice and data at the same time and prefer the faster data speeds. Through my company I can get the phone on Verizon and upgrade each year regardless of the two year contract. With AT&T I have to wait two years to upgrade the phone. So if the Verizon world feature is seamless, I would go with that.

Thanks for the feedback!
