In addition to the three GM iPhone and Android apps for OnStar, myCadillac and myChevrolet already reported last week, the company (which just today filed for a public stock offering) has released two more apps for the iOS and Android systems -- myBuick and myGMC, due to be released this week. Audi, meanwhile, has unveiled a forthcoming iPhone app that focuses on statistics and performance reports. The Audi application uses the existing OBD-II port, meaning many existing models can use the software.
