Here's your ticket to instantly streaming movies and TV shows to your mobile device without the juggernaut of movie rental. Search by name and sort by genre, just like on the Netflix Web site, then watch videos from your instant queue on your phone. If you're running Android, be sure to check and see if the app supports your device and operating system (OS) version.
The main complaint with the Netflix app is that it only allows you to sort your instant queue -- and that only poorly according to some. If you want to sort your disc queue, you'll need another app, such as iPhlix (Apple) and NetQ (Android) (see next section).
