Car-Sharing Firm ZipCar Releases iPhone App
ZipCar has released a much-anticipated iPhone app that works directly with the car-sharing firm's reservation system. ZipCar lets members rent cars by the hour, locating cars all over cities in which the firm operates. The iPhone app combines location with immediacy to make it even easier to get a car when and where you need it. The app also locks and unlocks the car and can remotely honk its horn, so you can find it.
