Great functionality but could play nicer with iPhone.

The functionality and convenience of having one number that goes to all devices is without a doubt very efficient. The reliability of the service is very hard. However, the ability of Google voice to work with the iPhone contacts is not as smooth as it should be. The favorites are not readily available. And the display of contacts is cumbersome. Except for the small piece of the application which is not playing nice with iPhone I really enjoy the app.
