Not for the mobile phone business obviously since the two companies produce very different phones and have different design cultures but Nokia owns one of the largest mapping data in the world and receives updates from delivery companies such as FedEx and UPS to keep its map data current.
These companies drive far more miles than Google does with its Street View cars. Apple is in serious need for a relatively quick fix of its mapping data and for some reason it doesn’t seem to be getting the necessary details from TomTom, OpenStreetMap, and its other partners. Nokia is in such a dire need for some serious cash injection that it is even considering to sell the building that it uses for its headquarters in Espoo and lease it from the new owners. It’s in the interest of both companies to consider this option which they surely must have behind closed doors.
While licensing map data might be an alternative, the baggage that comes with licensing is the exact reason why Apple pursued a mapping solution of its own. Another possibility, remote as it may be, is to acquire the mapping division and license the content back to Nokia and Microsoft.
