How to sync music from my iphone onto my laptop?

Somehow my music all got deleted from my itunes and I wanna put it back.
But all it says when I plug it in to my laptop I can only sync the music from my computer onto my phone - and I wanna do the opposite of that.
I hope this makes as much sense as I think it does.

What should I ask for this Christmas? - 1

I can't decide and my mom is making me give her the list today lol.
I already have an iPhone but its only a 4 and my mom is making me wait until my birthday to get the 5s.
I'm 14 and a dancer and a total girly girl. I already have an iPhone, laptop, UGG boots, plenty of makeup, clothes, Nook HD and a TV. My parents won't buy me anymore of what I already have so what else should I get that's not on the list?
I'm thinking about maybe an iPad mini or Pandora bracelet or my mom suggested a bigger tv. Please please help!
And also please don't say I'm spoiled or ungrateful my parents are willing and kind to buy me these things and I know I'm fortunate and there are less fortunate people out there. My family donates toys and clothes to orphaned kids every Christmas.

I dropped my iphone in my cereal?

I managed to get the first half of my new iphone 5s in milk. The first half meaning only the too of it which means like the camera and part of the touch screen. I had an otterbox on which helps a little bit, but it is definitely not waterproof. It was in the milk for probaly like 2 seconds. I put it in rice and it seems to be working fine. Is there anything else I should do?

It was stupidity and my parents will kill me if it stops working since my carrier is virgin mobile where it costs around $600 for the phone.
