Iphone 4S Volume not Working?

My iphone 4S volume is not working. I have tried everything. I spent 50$ on apple support and they couldnt do anything, all they did was get me to restore my phone and called it "professional". When i hit the volume change button nothing comes up and i can't change it in a video or anything. Its silent but the ringer volume works. I'm going insane because i can't listen to music please help! Iv tried brushing out the jack and charger and it doesn't work. I turn it on and off (Hold home and off button and just off button) and after that the volume works for 5 seconds then doesn't work. Please help

Sprint iphone bought off craigslist still active on other account?

I bought a Sprint iPhone 4 off of Craigslist andwhen I took it up to Sprint I found out it was active on the guy who sold it to me, his account. He still owes money for his contract. They told me the only way it would work was for him to pay it off. Is this true? Could I get it jail broken and it work on my Sprint account?

How to resume a download on iTunes?

So I bought an episode of a show on iTunes and it was downloading to my iPhone. I accidentally canceled it and I want to resume it now. When I go to the download menu, it says no active downloads and when I go to the purchased menu, it says watch but not download. So it's basically acting like its already downloaded. But it's not. How do I download the rest of it? I tried deleting it and redownloading but it won't let me delete it either.

Why do I look so bad in some photos?

Some photos I look really good in. My hair, skin, facial features and everything looks natural, but others look like a completely weird version of me, especially photos taken with the iphone 4 camera or flash photography.
