You right, it is easy, that's why I don't get why he didn't do it. Go to the contact section of the Apple site, then look at the right side bar and it says "Corporate Address" Hell, the guy could of drove there and maybe would of gotten some Apple gift cards or something. http://www.apple.com/contact/
Apple care wouldn't know about iPhone prototypes, they would think it's a prank call. Saying "Hey, I think I found a iPhone prototype, it's square" Is going to mean shit to some one that doesn't know anything about the iPhone prototypes. The battery was dead? Yeah I guess no one at gizmodo had a iphone charger.
No, it's not finders keeps that's what little 5 year olds say, Calling a call center and telling them that you have found a iPhone isn't going to do much. The phone SHOULD NOT HAVE LEFT THE BAR. It should of been turned into the bar owners this is the LAW in Cali, the guy stole it by taking it home. Gizmodo bought stolen property. End.
