A new version of
Navizon has been released. This version contains a new service called
Mobfindr that will let anyone locate their phone (or locate their friends) simply by sending an SMS with a pass-code.
This can be very useful if you ever lose your device or try to locate one of your friends (as long as they are willing to share their pass-code with you).
This service is triggered only when it receives an SMS asking for the geographic location, which means that it will not have any impact on the battery life or the performance of the phone.
