I'm not in a country that does this really, but if carriers usually charge you for data tethering from your phone, I can't see how Nintendo could get away with it. Last I heard Apple didn't even allow tethering apps on the app store.wow, they're going all "on the go" with that thing. I take it there will be an automatically connect switch with internet over phone option as well in that app. Could be nice. Could finally make Network Companies make the switch to "no more roaming".
Smart imo.
