Well, given that the police had to resort to linking it to an actual person via a supermarket loyalty card, it's reasonably to assume there was nothing on the phone itself (stored numbers for Home, Mum, Work, etc) tying to down to anyone.
Assuming an honest driver, once s/he had exhausted the obvious data sources (addressbook, etc), it's not too much of a leap for them to make to see if there might be identifying information elsewhere. I.e. in the phone's photos.
But I agree - totally *possible* that s/he nicked it, took it home, saw the photos and then "remembered" to hand it in :-)
