How to get back my old default YouTube app on my iPhone?

I updated my iPhone 3GS software today and my YouTube app disappeared. I found another one and downloaded it but I hate it. How can I get back the old one? There are thousands of YouTube related apps in the App Store so a specific name would be helpful.

It would be great to have my old one back with my saved videos. I backed up my iPhone to my MacBook before updating, but I don't know if that will help

You can re-download the YouTube app to your iPhone on iTunes store for free.

  • Where can I get IPhone Pink flower default wallpaper? I updated someone's iPhone and the new 6.1.3 update for iPhone 4S deleted it and now I need to find where to get it. It was a wallpaper that was always there and now I replaced with another one but I need that wallpaper! It's a pink flower facing sideways to the left and it has water droplets on it. I'm sure you have seen it. Please give me the link or download for it!
  • Old Youtube App for iPhone 4? So instead of updating my iPhone to ios 6 I decided to keep it at ios 5. I did this so I could keep the old YouTube App and I would not lose all my favorites (I had many). I couldn't transfer all of them to my youtube account because when I tried it would just transfer some. I go on today and none of the favorites are there. I tried turning it off and on again and they're still not there. What to do?
  • IPhone/iPad yellow notes the default app? Can anyone tell me why although I have a number of notes in my yellow notes default app on my iPad/iPhone, the latest notes are disappearing into thin air after a few days, yet ones I added at the beginning are still there? How can I retrieve my lost notes please? I use only one email account.
  • I've been so fustrated with trying to get my old iCloud account off my old iPhone I forgot the password and recovery key to my iCloud account. I've called Apple and sent a receipt for proof of purchase, but they said it's invalid, because the SN doesn't match which doesn't make sense. Is there another way to just erase everything off the phone myself?
