TomTom (Tele Atlas) and Here (Navteq) offline vector maps support
There is already an option to buy offline vector map with Mapsforge OSM data as an in-app purchase in Locus. That will be a great advantage to have an option to buy a vector map with TomTom or Here data. Both of these companies are the major professional worldwide map providers. And they still have more official information than OSM has, especially about addresses and roads. Additionally using of TomTom and Here maps can give a way to get offline search (address and POI) and offline routing (pedestrian, bike and car).
