International roaming would be cool, but from reading onther posts I don't think its too high up on the priority list. The US one just arrived, but who knows. usually when i travel the first thing i do is buy a sim, usually works out to be cheaper than most roaming packages.
Yea, I'd agree that it would be a nice option, but buying a SIM when you get wherever you're going is the cheapest route. Their data only rates are quite cheap and you can use google dialer to then make any calls with data or for free over WiFi.
