There are a lot of App Store submissions and works-in-progress that trigger anticipatory drooling here at TUAW (Sling Mobile! Sling Mobile!), among them the program guide and movie finder i. TV; we first saw it a few weeks ago and I've been checking every day to see if it's shipped. Now you can download this free tool from the App Store and see for yourself what's so exciting. (The promo video on the i.tv site borrows heavily from Apple's 1984 ad and the Apple TV intro, so clearly there's an effort to brand this app as 'revolutionary.')
The heart of i. TV (App Store link) is a TV listings browser, which connects to the free data feed from the i.tv site (registration is required), including synopses and cast info. You can select your zip code and programming provider (the app currently supports US and Canadian TV listings only) and the current schedules are there at your fingertips; you can rate, review, filter or flag shows as favorites and optionally share your feedback with other i.TV users.
Along with the TV content, the movies section of the app lets you browse by title or by nearby theaters, and watch streamed trailers of your selected films. Trailers and previews of TV shows are also included. The UI is clean and the app is easy to navigate; I was able to find show listings quickly for several series.
As cool as the initial version of i.TV appears to be, the development directions are exponentially cooler. Future versions of the app are planned that will include remote DVR programming (ooh!), IR blaster integration (yes!), DVD rentals (ahh!), movie ticket purchases and even the ability to watch full TV shows streamed from the programming source (hmm.).
Note that there is another app with a similar name, ITV, which provides French television listings and goes for $2.99 US.
