AT&T Navigator iPhone app
US carrier AT&T has released an official Navigator app for the iPhone. The app mirrors software available for other phones, providing turn-by-turn car navigation to addresses entered on the go, or else on a computer ahead of a trip. Driving commands are spoken aloud, and traffic updates as well as rerouting are handled in real-time.
Users can additionally search for gas stations according to price, and download map updates automatically at no extra cost. The app itself is free, but attached to a $10 monthly subscription, which is added to a person's AT&T bill. The company also warns that the app can be deleted without canceling the subscription. iPhone 3.0 firmware is required, along with an iPhone 3G or 3G S.
