A new update to TripIt’s travel organizer application for the iPhone and iPod touch now allows users to edit itinerary information directly on their device. TripIt is a companion application for users of the popular travel management web service, providing users with simple access to their TripIt itineraries while on the go. In prior versions, the TripIt app provided a read-only view of itineraries with a visit to the web site required to modify any information. Version 2.4 of the iPhone app introduces the ability to create new trips, add plans to existing trips and delete content directly from within the app. The new version also now provides notification of conflicting flight information and an improved login experience. TripIt 2.4 requires iOS 4.0 or later and is available from the App Store as either a free, ad-supported version or a $2 ad-free version. A free account at TripIt.com is required to use the app.
