Google has launched the official iPhone app for Google Voice, the communication service launched back in 2009.Though there was already an HTML5-based Google Voice app for iOS 3.0 and WebOS, this is the first time Google Voice users get a native app for the iPhone.

The app brings all the excellent Google Voice features to your device, including cheap rates for international calls, free texts to U.S. numbers and voicemail transcription. In addition to these, Google Voice for iPhone includes other benefits such as push notifications for new voicemails and text messages, and support for Direct Access Numbers, which makes calls easier and faster to connect.

You can download Google Voice for iPhone from the App Store now. You'll need iOS 3.1 or later, and a valid Google Voice account. Remember that Google Voice is currently only available in the United States.
