I was also surprised by this. In Canada my iPod showed a location more than 1,000 miles away based on a national ISP. In the US, it shows the correct address, and puts the dot on the satellite image perfectly, entirely based on IP. The iPhone GPS is also more accurate in the US, perhaps incorporating cell tower triangulation, able to accurately show me moving about on a small deck with an accuracy of ± 3 feet. Google provides incredible sat imagery here to view that. Neither of these can be counted on, but they are amazing when they happen. -- You received this message because you are subscribed to the Google Groups "iPhoneWebDev" group.
