Frommer’s has announced a collection of Travel Guides for iPhone and iPod Touch. The app features local travel tips, restaurant and hotel reviews, and bonus features such as location-based services, interactive maps, and web and phone links. A demo video is embedded above.

Frommer’s New York City, San Francisco, London and Paris are available for purchase and download via the Apple App Store and iTunes.

This is a nice example of how interactive applications can replace books and be a smart alternative to ebooks.

A guidebook like this, along with some travel podcasts and location-based social media apps, could make traditional Travel Guides obsolete.
