!!! Project servers were closed in the beginning of 2012 because the project was not actual anymore (massivity using Android and iOS devices instead of "simple" mobile phones). But source codes are always available as usual !!! A simple mobile j2me/web application that provides positioning of mobile devices connected to GSM/UMTS network or via GPS and lets you share location info by SMS or email. This project also contains GeoSignature Server j2ee application.
