GPS.PI 4.0.

This program exchanges geographical position points by SMS or Email (GPRS, Bt, Wifi) services of cellular phone network.

This version works with any Pocket PC Phone Edition devices.
MS Smartphone version is available too.
You can easily find your friends and follow his/her positions on the map or satellites photo.
This program was dedicated to use
with Pocket PC Phone Edition devices.
But this is not a limit.
If both sides (you and your friends) have Phone Edition devices with connected any GPS Receivers, all runs automatically. Just by one touch of screen.
In case, somebody hasn't a Phone Edition, but only a GPS Receiver, and any type of cellular network phone: the position can be send by the manually written SMS or Email. The Phone Edition device receives this messages and automatically put points on the map image - no special manipulations need.
Best of all: you can receive any SMS or Email messages even if you have not this program running. Later you can launch this program at any time, and restore all received positions.
