Netflix has updated their application for Apple’s iPad, iPhone and iPod touch, bringing with it an entire new interface for all iOS devices. The company will also be providing access to tons of television content, all of which will be available for streaming. In addition to those improvements, the new version fixes some “stability issues” and adds new region support for countries such as Canada and Latin America.

Netflix has finally made good on their promise to release a video app for the iPhone and iPod touch to match their early iPad offering. Now Netflix subscribers can stream their Watch Instantly shows to their handheld devices, as well as search and manage their queue. In addition to renting DVDs throuh the mail, Netflix has a large library of films and TV shows available to watch via streaming video. Subscribers to the service get unlimited access to as much of the “Watch Instantly” selections as they want.

Netflix is the popular movie service where users can create a list of DVDs they want to watch, which are then mailed one at a time. In addition, Netflix has recently added a streaming component (“Watch Instantly“) where you can watch from your computer.

The problem with this, of course, is that the service simply isn’t obsessive enough. Sure, you can update your queue whenever you’re at your computer, but what if you’re out walking around, and you suddenly realize you need to watch The 400 Blows this week, or move Tommy Boy to the top of your list? What then?

Fortunately, there are a slew of apps for managing your Netflix account from your iPhone or iPod touch, and today I’m looking at three: two free, and one available for $0.99.
