Citysearch Launches iPhone App

West Hollywood-based Citysearch, which operates online guides to local areas, said Thursday afternoon that it has launched an application for the iPhone and iPod touch. The new app, available in the Apple App Store, allows users to write reviews and access content from Citysearch. Citysearch said the new app uses the iPhone's location-based technology to identify local restaurants, hotels, shops, and other businesses near to users. The application is free for users. Citysearch is owned by IAC.
