TomTom has released a new iPhone app that expands upon its taxi hailing service that was launched in Amsterdam back in September. The original service required passengers to hail a cab from a specific terminal, while the new iPhone app can be used to order a cab to any location. The TomTomTaxi app also features the ability to learn about the taxi drivers and even choose favorite drivers when they have a good experience. While the app is currently limited to iOS an Android version is currently in production, however no firm release date has been given.
