new 7.1 iphone software update messes up my iphone 4s volume.

So I updated my iPhone 4s software to the new 7.1 version and now my volume/sound doesnt work. I can't listen to videos( and video texts) or music unless I use headphones. Very inconvenient to say the least. Is there a fix? Is anyone else having this problem with their 4s?

I also hear of problems with texting (sending/receiving) from 3rd party friends. (ex friends of friend)

P.S. I tried a hard restart multiple times and did a restore from iTuens... no luck.
