But an unsalted hash is only better than plaintext if the attacker doesn't know enough/care enough to use a rainbow table. At that point, why do you care if it was hashed or not?
I suggest that the pawn shop I've just described employs someone with considerably more advanced cracking skills: they receive several stolen phones and computers a day and have a tidy business on the side selling data and stolen passwords to identity thieves.
I made this scenario up to illustrate that if there is valuable data that can be cracked open, the "market" will organize itself in such a way to get ahold of it.
i.e. basically none.
