Run youtube in background on iphone 4? Ios6?

So i downloaded ios6, which deleted the default youtube app from my iphone. I downloaded the free youtube app in the app store, but now when i play a video, then go to the homepage and double click the home button to try and play the video in the background, that is not an option.

Instead of using the youtube app, use youtube on Safari. Just change tabs or click the home button, then do the same thing as before

Apple has officially released iOS 6, the latest update to the mobile OS. A dynamic menu bar that shifts color depending on the background.
