If you used Maps application with your iPhone 3G recently (let us say in seven last days), you perhaps determined a small change in display. Indeed, since last September 15th, Google slightly changed the way our position appears on the card with GPS. From now on, a transparent blue disc, of a more or less important diameter, encircles the blue point of location, pointing out so the degree of precision. If the point is encircled with no disc, precision is optimum. If there is a disc, precision is not optimum, and this according to the breadth of the disc. To get this new display, it is enough to use Maps, the update being in even the card!
