Android Question How top retrieve location over mobile network

hi,

I have successfully obtained relatively accurate position with Location.Manager over wifi. With Wifi absent however, I get the "coarse" position. When I activate data access over mobile network on my phone (and I can connect to internet) I still get the "coarse" result. Is there a way of getting the "fine" results with data enabled over mobile access ? If not, would it be possible to go to google maps and retrieve my location ? This info is for a mobile app. on a phone not tethered to wifi.

Thanks

Chris
