On the heels of making Google Voice and Hangouts play nice with one another, Google is freshening up its long-neglected Google Voice app on iOS. After close to a year without an update, a new version that went out today nixes the many of the bright blues and greens for a black and white interface Google says is more in tune with design cues from iOS 7. The only thing thats out of place is where you type and send messages, which still looks like the old-school, bubbly iOS of yore.
