Take a look on this print screen map view. Its taken from Apple iPhone 3G guys. Yes now you could have the XRoad G-Map (GPS navigation software) into your iPhone 3G. The price is about $20 but it has less technology of can’t download maps, directions through internet as well as turn by turn direction like other GPS portable features. This XRoad G-Map GPS-iPhone application has supported with 900MB memory which is enough to store local maps. Source
