Netflix today announced a new app for the iPhone and iPod touch devices. The new app allows users to stream the company’s ‘Watch Instantly’ content over both Wi-Fi and 3G networks.

“Apple has changed the game for mobile devices,” said Reed Hastings, Netflix co-founder and chief executive officer, in a statement. “We’re excited that our members can now carry Netflix around in their pockets and instantly watch movies and TV shows streamed from Netflix right to their iPhone or iPod touch.”

The new Netflix app is available for free at the App Store and requires a membership starting at $8.99 to view content.

Hastings originally previewed the Netflix app back at Apple’s Worldwide Developer Conference (WWDC) in June, during Steve Job’s unveiling of the iPhone 4. Netflix takes advantage of Apple’s HTTP adaptive bitrate streaming technology, which it says is the reason the company is able to stream video over AT&T’s 3G network.

Netflix currently boasts over 15 million members enrolled in its subscription service, which also includes DVDs delivered by mail.
