WorldMate is an awesome app to organize your trip itinerary, doing all the meticulous filing and sorting for you. Just create an account with them and forward all your flight & hotel booking confirmations emails to firstname.lastname@example.org - the app will automatically format all of the data into your account so it is very easy to get an overview and see what flights/nights you haven't accounted for yet. It completely removes the hassle of printing and looking for booking details or confirmation codes, and will update as time passes to always show your next flight/stay when you open your trip.
There are also other features for price alerts, counter offers, flight search and time/currency converters, but I haven't tried those yet. This app is amazing for itinerary organization and management, and thats what I use it for.
