If your target device does not support JSR 179 - and you wish to get location in your app - you can try:
1) For accuracy - Ask the user to pair the phone which any Bluetooth compliant GPS receiver use JSR 82 to fetch the location data from BT device - http://www.developer.nokia.com/Commu..._Bluetooth_GPS
2) For Less accuracy - You can try to capture Cell tower based location provided by CBS message - http://www.developer.nokia.com/Commu...ture_Cell_Info
3) For New Nokia Asha devices - they support Positioning CellID via JSR 179. - http://www.developer.nokia.com/Commu...on_via_Cell_ID
