Back of my iphone 4 looks blurry when taking pictures, Why?

I have an iphone 4 had it for awhile but about a week ago the back camera is blurry. I've had this happen before but it looked like there was steam in the camera lens and I let that air out and it went back to normal. So what's the problem this time? My mom isn't willing to buy me another iphone because before I went to a concert and the speakers messed up half the screen. If its the software acting up can I get a free new one?

IPhone 5 16GB or 32GB? Which is best for me?

-I have tons of music. 2000 songs. (Adding more)
-I don't have a lot of photos. 62 photos
-Definitely don't have a lot of apps. 12. (Facebook, Twitter, Tumblr, ScoreCenter, Pandora, YouTube, iFunny, FML, Skype, Kik, Weather Channel, iTorch.)

I have an iPhone 4 right now (8GB) and I'm hoping to upgrade to an iPhone 5. Either a 16GB or a 32GB. I'm willing to spend the money for a 32GB, though I'd rather not. Which would be best? My music currently only takes up 3GB and I still have a GB of space left.

Added (1). @Kate, I decreased the bitrate to 64.So, the biggest song I have is around 2.3MB.

IOS 7 Beta Installation Problem?

Basically, I was trying to install iOS 7 beta on my iPhone 4S recently and everything went well. When it came to the end of the activation, it said activation didn't work. Because I needed a SIM card. (Not the activation error about UDID registration) How can I install iOS 7 without the activation? So when it's installed it's automatically done?
This is what I did:
1. Opened up iTunes and restored my phone to the latest version (6.1.3)
I read online that you had to do that first. And then, the activation part of where I didn't have a SIM card came and it bricked my iPhone. My uncle fixed it for me but I really want iOS 7 even though it's a beta. Please help me someone. 10 points, best answer and 5 star rating for the person who helps me the most.
