Google Voice is by invitation only still, but Google said it is sending out invitations daily to those who have registered. The app is available to Android phone users at the Android Market, but BlackBerry users must download it from m./voice.

A video at Google's blog explains some of the functions. Users can also place calls and send SMS messages.

The application means a user can access voicemail, read SMS messages sent to Google Voice and access call history. The call can be made directly from the phone's address book because the app is integrated with the phone, Google said. The new apps allow users to make calls and send SMS with a Google Voice number directly from their Android or BlackBerry smartphone.
