To be a little more specific, it's "North America," not just the US.
I took my 8830 to Canada (Nova Scotia). It was international roaming and I was NOT able to use a GSM SIM.
But, my understanding is that if you have the phone in Europe, you have the choice of "Sprint" GSM (meaning you have a US phone number and get billed by Sprint) or you can stick in "any" GSM SIM and be billed by that carrier (or pre-paid). Notice that "any" is in quotes. You may not be able to get Blackberry service if you go this route.
