Google Voice gets updated: SMS updates by email
While seemingly a minor update for Google Voice, they've added SMS Updates by Email. Check it out under your settings menu. Essentially, all your messages will be properly threaded and pushed to your email--you can even respond directly from the email. Even though Apple blocked Google's app recently, Google is making every move to make it work seamlessly with the device!
