Just sell it I'd say.
I once sold a totally destroyed iphone 4 I found on the street on eBay for £114, that was near when they came out though. By totally destroyed I mean the front glass was smashed, rear glass wasn't even there, the phone was slightly bent.
I literally listed it on eBay as "Totally Destroyed iPhone", took a photo of front and back, wrote "what you see is what you get" in description and some dude offered me £114!
