Iphone 4 back and front screen replacement?

I currently have a iphone 4 ; the front screen is cracked a little. It has a black front and a white transparent back. Is there any site I can send it too to have the screen fixed and made back completely white? Or just put on a new white front?

Why is my iPhone memory space taken up?

It is 8gb and I understand that I only get to use 6.4gb because of preset apps and what not, but for some reason my iPhone is saying I have 4.4gb in audio used though I only have 695 songs. I was told I should be able to have a little over 1000 songs and pictures with this iPhone and I'm quite confused. Does anyone have any idea of what could be the problem or am I misunderstanding something? Thanks for the help!

By the way… My iPhone has the latest software update, I barely have any apps (facebook, twitter, instagram), and I restored my phone (but with backup so I have my previous music, contacts, messages, calls). The phone is only a few months old and it is a white iPhone 4.

Reducing ping or lag when I use my internet?

When I play computer games such as league of legends, my ping shoots up to about 400ms. I believe it to be caused by the Xbox and wii in my household streaming Netflix movies and usage of Wi-Fi on an iPod and iPhone. Is this problem caused by my modem, router, Internet speed, or ISP. Or do I simply just take turns where only one person can use Netflix at a time etc.

I downloaded TV shows to my iTunes, deleted them, and they still show up?

Okay so a while ago, I downloaded TV shows to my iTunes on my computer. When I was finished, I deleted them all. Every time I plug in my iPhone, after it syncs, the episodes begin to download again on my computer. I delete them again. Next time I plug in, same thing.

Which made me think that they were stored on my iphone. Can't find them anywhere. No where on itunes anymore. But they still keep showing up! How can I just delete them for good?

How much is it to break an AT&T contract?

Keep in mind, I'm a 13 year old, I don't know very many things about contracts.

I got a Samsung Flight 2 about 11 months ago. I'm signed up for the two year contract, and I want to get a new phone when the first year is up. But how much would I have to pay to break a contract? I plan on getting the Iphone 4s. Or can I upgrade, and then I don't have to pay anything at all?

And for anyone who is thinking I'm ungrateful little brat, I'm going to earn money from my job (I walk my neighbors dog) and save it up, and then get money from my birthday, and use it for that. Any extra expenses that my parents have to pay is how much less I'm getting for Christmas. Therefore, I don't think I'm too rotten.
