I'm lacking an iPhone myself so excuse me if my questions are stupid. I'm interested in hearing about some technology aspects behind the POI collector (unless these are terribly secret). I assume that the POI collector not only lets you collect new POIs but also modify existing ones. For this, the existing ones must be shown as active elements on the map that the device displays. Given that the OSM server proper is too slow to answer real-time "give me POIs in my vicinity" queries, and given that XAPI is not generally reliable for anything commercial grade, I assume that you are using your own XAPI-like POI database which tracks changes from the main OSM server and feeds them to the iPhone users, is that correct? Are you simply getting a feed that is close to real-time as possible and then let the device send updates directly to the OSM server, and what do you do in the hopefully rare case of an editing conflict?
