I'm getting seriously fed up with itunes?

Welp, they've done it again. Managed to piss me off. For some idiotic reason, iTunes is refusing to download music onto my iPhone. What a joy this life has turned out to be. Sometimes I just buy songs off of my phone, but I don't ALWAYS buy music off of iTunes. I can't download anything and to be honest, this is really just over the top annoying. I want to enjoy music on my iPhone, any music that I want. I can't download anything off of iTunes. If ANYONE knows a way to fix this. I would greatly appreciate it.

Can i get a warranty on my iPhone if i already bought it?

I dropped my iphone 5 in the toilet and was wondering if i can get a warranty and then a couple weeks later pretend like i dropped my phone in water so i can get it replaced for cheap? Can i get a warranty or insurance on my iphone right now?

What does this little icon mean?

The little icon right above "Books" in the status bar thingy, it always appears when I'm backing up my iPhone, I've clicked it but I'm not sure what it does. Someone care to tell me?

Waht can i do about my iPhone?

I dropped my iphone into the toilet and it works but a lot of the buttons don't work (left side of the keyboard, things i don't tap on open and such). What can i do? Would apple replace it if i said i dropped it and it stopped working or would they replace it even if i had water damage on it? I don't think i have insurance on it.

Is this a bad idea or a good idea?

This one kid at school said he'd buy me a phone (Galaxy S3) if I gave him my school lunch everyday for the rest of the year. (I want a phone really bad.) But at the same time, I'm really skinny (5'4 and 89 pounds) because I don't get to eat often (my parents are poor) yet he's 5'9 and 140 pounds. He says he doesn't have enough money to eat lunch but he has Jordan's, an iPhone 5S (yes the 5S), a Mercedes, and he lives in a mansion. We made this deal 2 weeks ago. He said that the phone would arrive in another 6 weeks since the phone's being shipped from China. I want a phone really bad so I can fit in and not feel left out. (Everyone at school hates me and I always get made fun of for my autism.)

Added (1). Also the social workers think my parents are neglecting me.

Added (2). Also he said he'd stop being my friend if I decided not to give him my lunch. He already gets lunch from his other classmates so I don't see why I should have to give my lunch to him, but like I said, free phone.

I dropped my iphone 5 in the toilet! What do i do?

So basically I'm practicing my golf swing in the mirror with my headphones in. My iphone was on the counter and on my backswing my phone somehow flew into the toilet. It dtill works pretty well but it is a little buggy (touch screen is only 90% acurate and sometimes presses buttons i didn't.) what can i do? Will apple fix it for free or anything?

Can a locked iPhone (on contract) work when you're on vacation overseas?

Call me lame but yeah, I've never got an iPhone on contract. I'm planning to get a 5s on contract. The thing is, I always go overseas every summer. I know that an iPhone on contract is "locked" when you go out of the US but its not like I'm going for good, right? Just for a vacaton.So, anyone?
