When you want to use location based information with i-mode devices all you have to do is prepare a CGI to manage an HTTP request from the device.
In your HTML add an anchor like this device:location?url=http://server/location.cgi. When clicked by the user, the device will place a request to your location.cgi CGI adding the location parameters using this structure: http://server/location.cgi?datum=AAA&unit=BBB&lat=XXX&lon=YYY. All you have to do is take the values and make your further elaboration.
