Are there any offline GPS or regional maps in iTunes store? Global ones only please (most I found are only USA or Canada -.-; ), or at least ones that cover major cities. I will be traveling to Europe next week, and China next month. Since most areas outside do not have wifi, it would be useful to have an offline GPS that only utilizes the GPS chipset, or at least a regional map of the area, showing where I am, the public transit system, major locations, etc. Thanks.
