If my iPhone gets sent away, will it clear everything?

So I dropped my phone then it wouldn't turn back on. So I tried charging it but it won't. I think I'm going to have to get it sent away for a new battery but I'm scared it will clear everything?

The thing is, my upgrade is this month and my new phone is due this week coming but I need my old phone as I haven't backed it up for almost a year and I want my music and photos on my new phone but I'm scared everything will get cleared then that'll be everything gone. I had nearly a thousand songs and 7,000 photos. I don't want them gone so is there anyway that I can save them? I'm not just going to download all those songs again as it will cost me another fortune as I always buy my songs off of iTunes. My phone is also insured but I really can't have anything cleared. So will it be okay or not?

Please give answers back in detail.

Iphone screen slowly faded black?

So last night I was super mad, and I threw my phone at a wall. After that, I picked my phone up, and the screen wasn't cracked, but it was like a purple-ish color, and after about 2 minutes, my phone screen went completely black. My phone still makes a noise when I plug it in to charge, but the screen is completely black. How can I fix this?

Icloud still on iphone i bought from someone?

I bought an iPhone, just to use like an iPod and the icloud from the other person is still on there. It says it still needs a password to delete it because the locate my iPhone thing is on and locked, any way to get rid of this without losing the stuff I just put on the apps I just put on the iPhone? Oh! I do have an iTunes account with a lot of apps I want but I'm afraid to plug it in cause it might think it's not my iPhone.

Why won't my iTunes let me sync my songs?

I have restarted my laptop, un-installed iTunes then reinstalled it again several times. And after I do any of them I will plug my iPhone 4S into the USB (with cable) port and it'll start syncing my music but then a notification will pop up and say my music can't be found. But all my music is still in the iTunes. I don't get it?
