When I was using my Z550i bought from vodafone in Australia, I was able to see my current location/suburb on the standby screen. But after unlocking it and using it in Singapore with my Singtel simcard, the location is no longer displayed. I've bought a S500i from HK and with the same vodafone simcard, I can't get the location to display either. I've already installed the internet and MMS settings from SE website but still doesn't work. Could anyone help?
