IPhone 5s lost:'! With iOS7 and iCloud account?

I lost my phone just 2 hours ago. What should i do? Would the person who finds it be able to unlock it? It's an iPhone 5s w iOS 7 I heard you can't unlock it and you can report it so thy can't use.

Did you install the Find My iPhone app? If so, you can use that to locate it. Start by calling your provider immediately and see what they tell you to do.

I recommend going outside.

or buying a new one.

The last 3 words would have really helped. There's an app called Find my iPhone that would have been ideal, if you didn't install it then you basically screwed yourself.

The person wouldn't be able to restore it without your Apple ID password but that doesn't mean it would end up in your hands once again.
