The Weather Channel has become the first cable network to create an application for Apple's iPhone and its near twin, the iPod Touch. The application, which does not require a download -- Apple refuses to allow the installation of third-party software in the devices -- takes advantage of the devices' touch-screen technology to deliver current, hourly and 10-day forecasts and weather maps from the Weather Channel. The application also provides severe weather alerts and a link to The Weather Channel Mobile Web the delivers information on traffic and airport delays.
