How to get itube on new iPhone?

I previously had a iPhone 3GS and I had itube installed on it. I got a new iPhone se but can't download itube off the App Store. I was wondering if there was a way I could either transfer my itube from my old iPhone, onto my new one, or somehow get itube off the internet and install it on my iPhone.

Ues

I'm assuming iTube was a jailbroken app, therefore the 3GS had to be jailbroken to get it.

If so, you'd have to do the same to the SE to get the app again.
