Netflix for iPad ios 5.1.1

Unfortunately you can only update to 5.1.1 for the ipad1

install netflix on ipad first gen.:
first make sure your iPad 1st. gen is on iOS 5.1.1 !
It is possible, a bit tricky, but possible. First, you'll need to download the Netflix app through iTunes on your computer, this will make it show up as "purchased" in your library. After that, open up the App Store on your iPad 1 and go to the 'purchased' tab. When you try to install it this way it will tell you that you need iOS 6 or higher, but will also ask if you would like to download an older version of the app. then click on download.
- again step by step:
1) Open up iTunes on your computer
2) Go to Store (left hand column) ->iTunes Store
3) Search for Netflix; - download the app
4) then open App Store on your iPad
5) Click on 'Purchased'
- you will have to install NetFlix by clicking on it as usual.
App Store will ask you: "Download an older version of this app. The current version requires iOS 6.0 or later, but you can download the last compatible version.",
then click on Download and it should finally work.

Netflix for iPad is only compatible with iOS 6.0 or later, so you'll need to update iOS to download the current version of the Netflix app from the App Store. This can be done by opening Settings, selecting General, then tapping Software Update, or by connecting the iPad to your computer and opening iTunes, which should prompt automatically if an update is available for iOS.
