I'm having issue with updating my iPhone 9?

I went into the future too 2019 and went to purchase an iPhone 9 that has a 15 mega pixel camera and has an eye detection sensor and it even remembers certain peoples voices and eyes.

I went back in time to show off to everyone. I thought I'll better put some music on. But the dam iTunes won't accept my phone. It says iTunes needs updating, but the latest update doesn't exist yet.

What shall I do?

I also have an issue about my playstation 10 the holographic screen keeps going black i keep using degraded uranium but it's still not working

You really took the time to make this up?
