Mapper

Click the button to run. Should work on Windows 32/64, Linux, Mac. Should create desktop shortcut so you can run it offline.

Spoofing Firefox

Enter 'about:config' in the Firefox address bar. Find the preference 'geo.wifi.uri' and change it to 'http://localhost:8085'. Now you can select any location by clicking on the map in Mapper, and this location will be reported to Firefox as 'my location'. Visit http://bemoko.com/blog/iphonegeo for a demo.

Spoofing Android Emulator

Should work automatically if emulator is running on localhost:5554.

GPS

Instead of clicking, Mapper can get your exact location from a bluetooth GPS device.

Before running Mapper, pair your GPS with the computer and configure a serial port connection. Windows Vista does this automatically after pairing. On Mac OS X sometimes it helps get a connection up if you remove the serial port, click Apply, then add the serial port again. Then run Mapper and select the serial port from the pop-up list at the bottom.
