My iPhone 4S, completely shut down for about an hour and won't turn on, any help?

I am quite worried due to the fact I have over 400 photos.

Try this First...
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
Wait for the Apple logo to Appear...
Usually takes about 15 - 20 Seconds... ( But can take Longer...)
Release the Buttons...
