Enable Google Latitude and Launch Maps on ROOTED G1′s ONLY in countries that it is disabled, e.g. UK.

Needs Superuser whitelist and latest firmware. If you’ve run Google Maps since last reboot, it will also need a reboot to stop the Maps app and refresh.

I’ve downloaded this to my phone and it works perfectly ….. oh the joys of having root!
