Ringer/volume isn't working on my iPhone 4S. What should I do?

Today, I found out that no sound is coming out from my iPhone, not even the sound it makes when you touch the screen or lock it. I tried to turn up the volume by pressing the side buttons, but the blocks are gone. I've tried to restart it and go to the settings too and nothing has happened. Sometimes it makes sounds, but it is only when I lock it or type in my passcode. And that is rarely. I'm getting really frustrated. There's even no sound when i play a video. Please help. Thank you!

How to get pictures and contacts off my Iphone?

Some one saw my mom's password on her iphone so she changed it and now does not know what she changed it to… (She is still learning how to use her iPhone) but she tried the wrong password too many times and now her iPhone is disabled. However she has a lot of pictures on it that she needs and a lot of contacts as well. I tried syncing it with iTunes to back it up before restoring it but I can't connect it because it says I need to unlock it before iTunes can connect. So all in all, how can i back it up or get the contacts and pictures off?
