This is no different than my Verizon Blackberry was.
It was CDMA in the US (Verizon, of course). It also came preloaded with a Vodaphone SIM card for use on Vodaphone & its partners when outside of the US.
You were advised to purchase an international call and/or data package before leaving on your trip.
The VWZ Blackberry phones were (are) locked to Vodaphone for GSM service, BUT if you had the phone ~6 months and paid your bills, they would unlock it for you. They unlocked my BB Storm 2 when I called and asked.
As an FYI, the CDMA/World BBs, even unlocked, wouldn't run on AT&T or T-Mobile in the US for 3G data as they only supported european GSM data frequencies.
Since the iPhone will support US GSM data networks (AT&T), I don't know if Verizon (or Sprint) will unlock the GSM portion on request like they would with Blackberry. I'm guessing they won't. At least not while you're under contract.
