This morning, an important news has been posted on google official blog : "Google voice for everyone".
Everyone ? Means I can try it from here (France), as I remember it was just available from U.S. before.
Good news ! I will try it as soon as possible.
But no... "everyone" finally means "everyone in the U.S.".
Even if U.S. is a big country with around 300k persons, we're around 6 800k staying outside U.S. !
