How to sync my iPhone over Wi-Fi with a new computer? - 1

Added (1). I've had the new computer for a while but i can only sync with the cable plugged in. I tried clicking "sync with iPhone over Wi-Fi" in iTunes when it's plugged in, but on my phone where it says "iTunes Wi-Fi sync", it's insisting that it should be syncing with my old computer, stating that the last over-Wi-Fi sync happened sometime in 2014 when I still had the old computer. How do I resolve this issue and get my phone to recognize my new computer?

Why does my iphone not load anything related to the internet?

My iphone has been pissing me off for the last damn time. A while back i downloaded a VPN called Onavo so i could get past my schools Wi-Fi blocks when i have spare time in class. But recently it glitched out and wouldn't connect to the server at all. So i deleted it and all of its content from my phone, go to re-install it and i can't connect to anything. Turned on and off my phone and still didn't work. Tried going closer to my internet router ( yes i'm connected to my internet ) and it STILL didn't work. I tried everything, it was to the point that i felt like breaking the phone in half that i started writing this question.

I'm connected to the internet, but nothing works. I looked this up on its own, didn't find anything Please Help ME

I accidentally deleted part of a video on my iPhone?

I was trying to trim it and ended up saving the part I wanted to trim and deleting the part I wanted to keep. Instead of selecting to save it as another clip, I chose "trim original". I know it's probably not possible, but I just wondered if there's any way to undo what I did and restore it back to the original length?
