IPhone 4s microphone problem? - 1

So yesterday I went out with my mates to the cinema and by accident some melted chocolate got onto my phone so I wiped it off and havn't gone on my phone since. But this morning when I facetimed my cousin she said my microphone sounded like it had something blocking it or something as I sounded very quiet and low pitched. When we finished talking I ended the call and videoed myself to see what she means. When i played the video back I completely understood what she meant by how quiet and low I sounded.
Could someone help me get it back to normal please?

How to sync my music to my iphone 4s?

Ok, so first of all, I have a Windows 8 computer. I downloaded iTunes onto this computer. Next, I downloaded songs from YouTube to mp3 converter to my iTunes account (by pressing save file to iTunes when downloading). The problem isn't necessarily getting the music to the iTunes, but getting these same songs to show up on my iPhone 4s. I signed into my iTunes account on my phone and the only music it is showing is the ONE song I actually purchased FROM iTunes. How do I get the rest of the music to appear onto my phone? I allowed for home sharing, I authorized my computer, my USB cable is plugged into both my computer and my phone, I just don't understand what I'm doing wrong, someone please help me, I want my music!

Call of duty app won't work on my iPhone?

I downloaded the call of duty app so I can use the clan wars feature since I created a clan. I logged into the app using my ghosts account but it doesn't load the app, it just says log in at the top but there's nothing for me to log into, it just says log in with a picture of the ghosts mask underneath and the app won't load. I really need it to work so I can properly set up my clan and stuff. Can anyone please tell me what might be the problem and how to fix it?
