Do location-aware apps work on the iPod touch? A lot of iPhone apps use GPS positioning to provide services. However, the iPod touch does not have GPS capabilities, although it does have WiFi-based location services, if I'm not mistaken. Do location-aware apps work on the iPod touch? If so, how well? I'm not interested in the iPhone right now, but since I live in a city, it would be cool to have a device that would allow me to call up maps and such when I'm walking around.
Yes. The "location services" work the same way on all iOS devices, while the specifics of how that data is obtained are hidden from the application.
