Both Aha Mobile and ALK Technologies have released new updates to their GPS-enabled apps for the iPhone. The Aha traffic and destination-finder app allows users to see the current traffic flow and travel time of roads, while delivering tools for locating nearby rest stops or coffee shops. With the latest 1.2 update users have the ability to speak into their iPhone and broadcast voice tweets to nearby drivers, as well as post the Aha Shouts automatically to either Twitter or FaceBook.
