I did something bad to my IPhone 5s. What do I do?

So just yesturday I was at my schools play working on the sound crew with the mics. And previously I was able to use a cord and attach my old iPod to it and play music through the speakers.
But when I tried attaching my iPhone the whole screen went bright blue. I was able to turn it off and then back on. But, me being stupid, just thought it wasn't plugged in properly, checked the cords and tried again. This time it turned black strips with fading colors. It was weird. And when I turned it off and tried to turn it back on it said to connect to iTunes.
So I did that last night and had to restore my iPhone. Lost a lot of pictures.
But on the ferry just now when I tried to plug in my earphones it wouldn't work. The earphones are totally fine but the sound is staticky and only comes in through the left ear. I looked into the headphone port and it looks fried. Is there anything I can do to fix it?! I don't have insurance on it.

Set up a repair.

  • Restore your purchases option, did I actually buy something? I got this neat manga app my iPhone and later when I went to delete some I saw a restore your purchases option. I was never prompted to give a credit card number and the download was free so I kinda freaked out. Does this option just mean that I can restore deleted mangas should I want to read them again? Manga is a type of comic for those wondering
  • Regarding sending something back with a warranty and returning something broken to a seller on amazon? I ordered a charger for my iPhone and it comes with a 18 month worry free warranty and my charger broke. So I was wondering can I return it to the seller in a envelope in my mailbox and same thing for the other thing that is broken. like or do I have to go to ups and ship it like that
  • Is there something wrong with my phone or is there something wrong with my mom's phone? Ok so when I attempt to call my mom, it doesn't ring it just goes straight to voicemail but doesn't show on my mom's phone that she had a missed called. My messages won't go through either, but her calls and messages come through to me. We both have iPhones and they are both on. I can text everyone else, call everyone else but her.
  • IPhone Suddenly slow after someone did something to it? I left my phone on my backpack… Someone, not sure who, messed with it. No pass code. Pressed down on screen hard and turned phone off I'm guessing from how it was when I returned 10 seconds later. Done in joking manner. My iPhone is suddenly pausing very often. Is there a fix? A setting? It just keeps freezing.
