Can you fix a bad ESN, MEID number for an iphone 4?

So today I bought an iPhone 4 off of craigslist and come to findout the phone was reported lost or stolen and I get robbed of 120 dollars.
I was just wondering is there anything I can do about that? Can I fix the ESN/MEID number back to being "CLEAN"?

Sorry but it's no way to fix that unless the original owner reports that they found the phone other than that it's a useless phone and can't be activated.

ESN is carrier specific - the carrier has blacklisted the phone, as a result of something akin to a reported stolen phone.
Other carriers, typically outside the US - can activate the phone.
