If the Sprint Galaxy S III did have all the internals to make it international roaming capable, I would be surprised. But if it doesn't, I'm happy just all the same. If I go to Canada, I won't even use my phone up there, as I can't stand Sprint's roaming rates, and Virgin Mobile Canada has some great plans, and GSM phones are a dime a dozen this day and age (I still have my Jailbroken & Carrier unlocked iPhone 3GS), so no matter where in the world I go, I'm set.
