I just checked with TMO about international roaming for GPRS too, since I'll be going to Canada in a couple weeks. It's $10 per MB in Canada, $15 per MB in the rest of the world. To me, that isn't that big of a deal, given that I am a moderately active email receipient, and used .99 MB last month. It will cost be a couple bucks to spend a week in Canada. Not that big of a deal.
