Google Voice today turned two. Google Voice was launched on Mar 11, 2009.
"We've been working hard to bring new features to Google Voice and make it available to as many users in as many places and on as many devices as possible.
As we mark this milestone, we want to thank all of our users in the Google Voice community. All of your support, feedback and stories have helped us improve the Google Voice experience," Google stated.
"We've seen the product evolve significantly over the last two years. In the last year alone, Google Voice went out of invite-only mode and became available to all US users, we brought calling to Gmail, launched apps for the iPhone, iPod Touch and iPad, Windows Phone 7, and made it possible to get the full set of Google Voice features on your existing mobile number by porting it to Google Voice."
