I bought a stolen iPhone 4 on craigslist?

I bought a phone from a guy on craigslist. It was an iphone4. When i was testing my sim there with him, everything worked! Then when i got home, an hour later i couldn't call or receive calls. It would say "we're sorry but this device has been blocked from network use" when i tried calling. I put my SIM card into my old iPhone 4.It doesn't work! My sim is blocked from use! When i called AT&T, they said the iPhone was reported STOLEN so it was blocked from usage. Are you serious? So I called the guy that I bought the phone from and he said he didn't report it stolen and that he wouldn't refund my money. I have his phone number still and his craiglist listing. He took my money and reported to AT&T to get a new phone from his insurance. Wicked.
Now are there any solutions to unblock the iPhone 4 and my sim card? Will restoring the iPhone work?
If i call the police about this will it be any use or help?
Also, would I get in trouble for having a reported stolen iPhone in my hands? I mean, I didn't steal it!

Why won't my iphone 4 let me touch the screen, and why does it keep restarting?

I had this phone for 10 months now.
It's been restarting for about 20 hours now.
It won't let me touch the screen, it stays on the lock screen, that says enter passcode.
I connected it to my computer, synced it ' and it worked fine again for a few hours.
Then a couple hours later, it wouldn't let me put in my passcode again.
But NOW, it keeps restarting over, and over again on it's own.
I tried to back it up, restore it and sync it to my computer, but it keeps turning on and off so it doesn't stay connected, so the process isn't able to complete and It still won't let me type in my passcode.
I don't know what to do.
How do you stop it from turning on and off?
How can i fix the screen again?
By the way.
*It has no water damage*
Anybody know how to fix this?
Please, any suggestions?
