Google would like Apple to return to Google Maps in a future version of iOS, chairman Eric Schmidt said today at an AllThingsD conference. "We would still really like them to use our maps," said Schmidt. "It would be easy for them to take the app in the store and put it as their basic one." The executive declined to comment on why Apple went with a proprietary system instead of continuing to use Google code and data, or whether the two companies are in talks.
