Unfortunately, I have no way of testing this new feature of the Google Voice app for Android since Google Voice is available only in the U.S. But if you have an Android Phone and you haven't used Google Voice yet, you might want to give it a shot. If you are using it already, expect an automatic update to happen soon. The new feature has something to do with the sending of notifications for new messages which previously takes around 15 minutes to be sent to a user's phone.
