Iphone keeps shutting down and not responding?

My iphone 4gs keeping shutting down on me. Like the screen goes black and pushing the power button to try and get it back on doesn't do anything. Neither does holding the power and home button at the same time. When I put it on the charger it doesn't do anything and it won't connect to iTtunes.anyone know what I can do to fix it other then go to the apple store (I have an appointment this evening but if I can do something now I'd like that), what the problem is, or if this has happened to them before. Thanks

Added (1). @DC I just got the phone in Jan.-Feb. Would it be an expired battery already?

The bad part about this is that I do NOT have Icloud. If someone could please please please help me it would mean so much these pictures mean a lot to me.

IPhone was stolen and I have find my iPhone app

So yesterday I got my iPhone 5 stolen. I had the app find my iPhone on it. I tracked it down for about half an hour but then I think the guy turned it off. It's been 24 hours now and now the iPhone on the app say "offline". The ind y iPhone app will notify me as soon as the location changes, so does this mean that the phone is still turned off? I already locked it and called my provider. They also locked it and if they try to put it into another provider it will appear that the phone was stolen and they can't use it at all. If thy reset my iPhone they will have to turn it on and then I can track it down right? If they reset it, will my iPhone still appear on the find my iPhone app or will it disappear? How would I know if they resetted my phone?

What happens if you spill a little bit of soda on your iphone?

So yesterday, I spilled a little bit of soda on the die of my iphone, but it wasn't really that bad to me. Just a little big on the side, but I don't think anything got into the internal. And now I feel like its running kind of slow, or am I just paranoid?

On the IPhone can an alarm still go off if?

Will an alarm still set off on an iPhone even if you are in "Do Not Disturb Mode" I never turn on the Do not disturb mode so i'm not sure if the phone stops ringing for everything or if an alarm will still go off. Cause blackberrys alarms will go off even of your in silent mode but this is my first iPhone so I have no close. My model is the iPhone 5 with all my updates!

P.S- anything else about "Do Not Disturb" mode that I should know?
