I cracked my iphone screen.now what?

I was in class and i put my dead iphone5 in my backpack since i couldnt text anymore and my backpack fell off my desk and it cracked real bad. I can't even touch it, my fingers got cut. When my mom got me the phone she said i have insurance. I don't want to tell her so i was going to go to sprint and see if it's covered tomorrow. Will they replace or repair it? Should i tell them a lie about how it broke or are they surely going to get it fixed/replaced? I have Sprint and it's an iphone5

Passcode problem with iphone?

So, i added some keyboards to my iphone. Then, i changed my passcode to the type where its the advanced passcode with the keyboard. And the keyboard was in russian and when i set my passcode, i set it in russian. But later, i decided to delete my russian keyboard in settings but the passcode still pops up when i slide to unlock. But when i "slide to unlock" the keyboard isn't in russian, so i can't type in the passcode so yeah

Why can't i get my music on my new iPhone?

I recently lost my iPhone 4, and today got an iPhone 5. The problem is if i go on iTunes from my new phone and try to download the music i already own it won't let me. Like if i click on an album i bought already it just says "purchased" and won't let me re download it. I don't have the music backed up on my computer.

Am i screwed?

Iphone won't play music on speaker?

My iPhone won't use the external speaker when I use the Music Player. It's NOT on silent mode. When I use the Music app, the volume control bar vanishes unless I plug in headphones. However, if I get a call, the phone WILL ring on ther external speaker and the call comes in just fine. It will not ring for a text message however. How can I fix this?

I have the iPhone 3S

Added (1). I did not drop the phone, or get water on it, it just randomly started doing it over a year ago, and all Apple told me was they couldn't figure it out and to buy a new phone.
