AT&T has released an update to its iPhone navigation app, AT&T Navigator. Version 1.5i offers an improved interface which now includes a speed limit display, with visual and audio alerts to notify the user when the limit is exceeded. A new option in the Recent Places menu allows users to easily navigate back to the origin of their last trip, while a "Shake-to-Go" feature automatically sets the route to go home when the iPhone is shaken.
