What if you lost or someone stole your iphone 5s?

I'm getting a iphone 5s but the biggest worry for me and my parents is losing it or someone stealing it.since its a new iphone, its more likely to get stolen than a basic phone or a old samsung phone. If you can get insurance on it, can apple replace the product? I'm really bad at remembering things so it is possible for me to lose it. I know there's a find my phone or something app that uses iCloud maybe that will help but thats only if you enable it. What if i forget to enable it? How do i enable it? Can someone please answer my question and tell me how to get the tracker thing on my phone or can i just get insurance for it? I'm new to apple devices

IPhone 4 Battery Dies Faster Than It Should?

Okay i Have A WHITE I Phone 4.i've had it since about June 1st of 2013. Recently i have been having some battery issues. Like right when i take it off the charger at 6:43am it goes to 99%. And is at like a low 70 or high 60% by 9:50-10:00am.sometimes i will notice my battery at 80% by 10 but its not very often. I have a field trip from 8AM tomorrow til MIDNIGHT and i need my phone to last me through that. I don't think i can charge my phone at anytime but I'm bringing my charger just in case. Is there any way i can help with saving my battery during the day (besides staying off of it). Like any settings i can change or something? All real answers will get a thumbs up.

Is texting free if your on Wi-Fi? (Iphone5)?

I used to have an iPhone 4 and my mom blocked text cause I texted like 100$ a day, but then a year later, I got an iPhone 5 (same phone number, just different phone) and I could text!

Can you transfer data from an old iphone to a new one with itunes?

I've had an iphone 4 for a while now without being paired to an itunes (my old computer was stolen and I haven't had a need for itunes).

Can this be done through icloud?

How to get an MP3 file onto iPhone 5?

So I have a regular iPhone 5 (not 5s or 5c) and I'm having troubles getting mp3 files that i've converted from youtube onto my phone. I've been trying to use www.youtube-mp3.org but when I convert the song and get the MP3 file into my iTunes library, I can't get it onto my phone? My brother has an iPhone 4 and it works perfect everytime for him. We both have iOS 7.It also previously worked for him when he had iOS 6, and it still works now for him.

So just to make it clear, I can get the mp3 files into my iTunes library, but from there I can't get them onto my iPhone. How can I get them onto my phone?

Any help would be greatly appreciated.

Also if it makes a difference, we use a laptop with iTunes 11.
