I followed up with the dev team a bit after our conversation, and it looks like the GPS and Cell tower location systems aren't actually separate. We ask for the location, and the phone OS sends answers which (generally) get more accurate over time, as the various systems report back with more information. The OS also says "here's how accurate I think this location is".

The problem you're running into is because the method that's fastest to respond - cell tower triangulation, in your neighborhood - isn't the most accurate due to the strength of the cell signal.

The developer I discussed this with theorized that we just need to check back with location services and update the map views once we saw a more accurate location guess come back.

We need to change the way the existing feature works, in other words, rather than add something that isn't there. That's in the development database, but it's not something that I can quote you a specific release on.
