You can use GV in Korea, I use it in Germany for 2 years already: Markus Göbel's Tech News Comments: Google's GrandCentral now also in Germany (Monday, July 16, 2007) You need an US IP number, but it's only necessary to complete the signup process an choose your phone number. After it you can forward it to any Gizmo5 account in the world. So you now have two options: 1.) Play with Proxies and get a temporary US IP number for the signup process 2.) Let your friends in the US complete the process for you. #2 is much easier, since those fake proxies are very slow and it seems that Google can detect Tor proxies now. At least I got the impression from my experiments. But for #2 you have to trust your Google password to another person, at least temporarily until you change it again.
