My friend took his iPhone to the Apple store since he was having some problems with it. I restored in DFU mode back to 2.2.1 and did not restore anything from backups. He was told his phone was jailbroken and they won't be able to exchange it but will try to fix it in store. 
He told them he doesn't know what JB is and have no idea what they are talking about.
is it possible for them to find out?
thanx
