My won't turn on, what do I do?

While going skating today I fell on the ice pretty hard. I brought my phone with me. I know what you're thinking why would I bring my phone on the ice, but it was in case my dad called. Anyway after falling I checked my phone (which had no exterior damage) and it didn't turn on. It still won't turn on and its been about 2 hours. Should I put it in rice? I didn't think it would have gotten too wet and shut shut off but my but was pretty soaked. What should I do? I should mention that I have an iPhone 4s

You should always take the battery out and wait 24 to 36 hours.
