While the initial rollout of Gmail Chat was meant for US-users only, word is going around that non-US users will also be able to take advantage of this feature, no thanks to the folks over at Google getting over excited with the latest development, leaking out the phone calling feature to non-US users albeit for just a few hours before rolling the update back. A statement from a Google spokesperson mentioned that “in our excitement to share voice calling, we got a little ahead of ourselves and, unintentionally, made it available for a brief time in some languages we don’t support yet. We’ve rolled back the feature, and apologize for any inconvenience. We launched it yesterday to US users and look forward to bringing localised versions to more people in the future.”
