Transferring old iPhone pics into new iPhone?

I bought an iPhone 5s yesterday. My old phone was a 4s. I had a lot of important pictures on it. How can I put them all in my new phone's camera roll? I really don't want to download them from iTunes because that will put them in a folder that can only be manipulated from my laptop. I want them in my regular camera roll. Can I use photo stream to send them to my new phone and save them from there? Is there any way I can use iCloud to transfer them?

Should i get a ipod 5 instead of iphone 4s?

Right now I have a iphone 4s but I'm on it 24/7 and I think I have a addiction to it! I'm always on it. I'm on it when I shop, at school, eating, and I always get yelled at saying not to be on my phone. I rather stay at home and be on my phone than go outside. So I think if I get a ipod 5 it would help because I can only use it where there's Wi-Fi! So should I get a ipod 5?

My iPhone 4 speakers won't work. How can I fix this?

When I was middle of eating ice, I've slightly dipped my iPhone 4 in my ice cream. It was only the right corner and also there was a little bit on the place where you insert the charger. I'm afraid to charge and tell my parents what have I done. Is there any home remedies that I can fix my iPhone 4?

IPhone broke by mistake, so I broke it more? What about my information?

My iPhone broke because I accidentally dropped it. The screen didn't turn on and the lock button was already broken. I brought it to a phone store to see if they can fix it, they said it would be a lot of money and I just get a new phone. Anyways, I'm worried about my information on it. I didn't have a phone number on it and only used it for Wi-Fi at home or where ever. But, I had my email accounts saved, and other things that were sort of important. I ended up breaking the phone even more. I took a hammer and broke it into pieces and then left it in water for a few minutes. If someone found my phone one day through the garbage, would they be able to get through my stuff or even fixed it? I broke it a lot, screen is off, just everything and left it to have water damage. Can someone tell me about my information? Will someone be able to have get my passwords, etc,? Even though I didn't write my passwords on the notes or anywhere in the phone. Am I safe or should I burn it with fire?
