How to listen YouTube on background on iOS 6 with iphone?

After i downloaded ios 6. I had to instal the youtube app. But somehow it isn't able to play on the background. Is there a way can I listen YouTube on background on iOS 6 with a iphone 4s with or without having to jailbreak?

You can't do it through the app, you have to do it through Safari. Start the video, then go to the home screen. Double-click the home button to get to the multitasking bar. Swipe so you go left, and there will be audio playback options - just press play.

What you need to do is:

Step 1: Launch Safari mobile browser and open YouTube.com
Step 2: Find a video you want to listen to in the background.
Step 2: When the video starts playing, press the Home button and the video will stop playing.
Step 3: Now double press on the Home button to bring up the multitasking bar.swipe to the right to find the media player buttons. Notice the Safari app icon to the right.
Step 4: Now tap the right-facing triangle play button and your video will start playing again and you will be able to listen audio track without seeing the video itself.
