For reference this is the feature I'm talking about, and it will import it to your Google account (though it wasn't useful for me, since my contacts were stored on my old phone rather than a SIM).

This kind of feature should be in the standard Android Contacts app IMO. But I can't comment on that, since I've not used a vanilla Android phone.

The Google Contacts 'find duplicates' feature did a passable job for the few duplicates I had, but I doubt it would fit some systems (e.g. matching together "Bill Posters" and "Bill Work") nor would it be worth the effort to try too hard. I guess that's a pain we have to live with.
