Expedia just updated its iPhone/iPod Touch app to add a digital hub called the Media Lounge.
The Media Lounge presents users hand-picked content meant to make travel easier and more enjoyable. It allows them to download premium content every month via iTunes – stuff like travel guides, wi-fi finders, and more. The first Media Lounge offering is Over, a photo-editing app (regularly $1.99) that enables travelers to personalize photos by adding text and artwork.
All this is in addition to the saving, booking, and itinerary tools already present in the app (which, outside the update, are also available to iPad users).
The Expedia app is available for free on the App Store.
