writes "In the recent release of iPhoto for iOS it appears that Apple have started using OpenStreetMap's data. Unfortunately, there are still some problems. Apple are currently not applying the necessary attribution to OSM; they are using an old (from April 2010) dump of the data; and they are not using the data in the USA. Fingers crossed apple works through these issues quickly!
Apple are now one of a growing list (including geocaching, and foursquare) to Switch2OSM."Link to Original Source
