OsmAnd for recording gps, audio and photos and looking at offline maps, Vespucci for OSM editing. Some like OSMtracker for recording gps, audio, photos as well as various features from a list of buttons. For addresses there is Keypad-Mapper.
And before realignmenting roads, know that Bing background might be misaligned. In Potlatch click GPS, and then align the background to GPS traces made by other people. Hold space and drag background.
Best field editor ever. There's so much stuff I would have never mapped without it. Do they have a "donate" button somewhere?
