Frequent fliers, take note: popular seat map website SeatGuru has released its iPhone app. The app is very similar to the website — it offers color-coded maps showing all of the seats and bathrooms on over 700 planes from 100 different airlines. If you've never used the site, all you do is plug in the airline, flight number, and date of your upcoming flight, and it'll give you seat recommendations. For example, you'll be told if certain seats have extended legroom, a power outlet, or if they have a restricted recline, like those pesky seats in front of the exit rows. The app also has real-time flight status updates from FlightAware and TripAdvisor-powered airfare comparisons. It's available now as a free download for the iPhone 3GS and the 3rd generation iPod touch or greater.
