Apple has let the Google Voice app GV Mobile back in the app store. They have also approved GV Connect which in my opinion is not as good as GV Mobile. The only problem I am having is I already bought GV Mobile from the Cydia store (GV Mobile was one of the only reasons I had jailbroken my iPhone). Sean Kovacs, the developer of GV Mobile, will be addressing this issue by making it free on the app store this coming Saturday night.
