Iphone 3gs black screen

I dropped my phone and then my screen started flickering, so I turned it off and laid it on my dresser and forgot to turn it back on, but now I can't get it to turn on. Like I keep getting a black screen and when I switch to the vibrate slot it'll vibrate but my screen stays black!

I've tried the hold button and home button but I can't see the Itunes Logo and it just stays black. I've reset it on Itunes but It still won't go away.

What does the Apple Store do with traded in iphones?

I cracked the back screen on my iphone, so today my mom took it in to get a new one. She comes home with a new phone and I had to go on the computer and sync it with my icloud. I lost basically everything, all my pictures from the past year, many contacts, and lots of apps. My old phone was fully functioning and had no real problems besides the cracked back screen. If I go into the same store tomorrow will they still have my phone and will I be able to get my info and pictures and such back? Or did the store already clean it out and is all my stuff gone?

What is a fun way to destroy my iPhone 5? - 1

My question is what can I do next that can awe my audience? Or what would something that would shock you? Just be realistic, not like throwing an iPhone against a wall. I was thinking of maybe a freeze test.
