Using ArcMap 10.1, I edited the coordinates within a shapefile.
They are long/lat but the point will not move to that new coordinate on the map.
I've tried clicking on the Longitude column in the attribute table and 'calculating geometry' but still nothing occurs.

Start editing that shapefile, double click on said point, right click on point and "move to" and it will give you an option to type in the x and y coordinates for where you want to move the point to. the drop down also gives options to change to DD or meters etc.
