Google has made some adjustments to the blue "My Location" circle on the mobile version of its mapping product.
If you're in a metropolitan area, the circle will be smaller. If you're in a rural area, the circle will become bigger. The reason behind the change and the sizes has to do with cell tower triangulation.
Google gathers data from cell towers near your phone to determine your location. If you're in an urban or suburban setting, you're likely to be close to more towers, giving Google the ability to pinpoint your location more precisely. If you're out in the boondocks, you have access to fewer or maybe just one tower, so the location is more approximate.
