yeah it looks shady... Or he could be real and just dumb as a doorknob... it's been known to happen... But i wouldn't trust it.
I recently bought an iphone of criagslist and the guy was really nice didn't know a thing about the phone which made me a little fishy... He wanted to meet up at my house, though i'm a cop i wont be testing my skills, but he happily agreed to meet me at a mcdonald's not to far from my house and it worked out great. Walked away with a 2 month of (reburbed most likely) 2g, 8gb iphone. I jailbroke it and gave it to my girlfriend... HAPPY ENDING
