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.
