What to do about my iphone 5s that got stolen?

My phone got stolen at school. I had the iphone tracking device and it went off twice during school but the school couldn't do anything cause it didn't have a direct classroom and also they turned it off right away. The phone is still currently off and i'm waiting til they turn it on again any tips on what i should do and if does get turned on what i should do then. Also what can i charge the person with etc.

Added (1). I have it to play sound and lock mode. I'm just waiting til they turn it on

Don't think about what to charge to the person with now, try to get the phone back first

Sign on to http://www.icloud.com/...icloud.com and put it in lost mode. With iphones you can also put a permanent message on the screen that can never be removed right from any browser.

I suggest to do what Artv said but there's nothing such as a phone finding app so don't ask about that

I highly agree with Artv it will lock the phone down so it can't be used and will send out messages to it's location. I would also suggest reporting it to the police, that way they can help track it down as well as the person that stole it.

You probably could charge the person with theft yes.
