Brad Isaac of Pocket PC Addict stumbled across a new piece of interesting software by JGUI (of Phone Profiles ... Seriously fame): GPS W.A.I.T (We Are In Touch)!

"This program exchanges the position point from the GPS by the SMS cellular phone network.

You can find your friend and see his/her position on the map or satellites photo.

Now you can check where and how far he/she is away from your current position.

This program is dedicated to use with Pocket PC Phone Edition devices. But this is not a limit.

If both side (you and your friend) have Phone Edition with connected GPS Receivers, all runs automatically. Just in one touch of screen.

If somebody has not a Phone Edition, but only GPS Rx and any type of cellular network phone. Then the position can be send by the manually edited SMS. The Phone Edition device will receive this message and automatically put to the map - no special manipulation need.

Best of all: every Phone Edition device can display up to 10 friends in one map, independently.

Features:

• show your actual position, speed, moving path
• show GPS satellites signals
• values are displayed in metric, imperial or nautical units
• manually or automatically select the map or photo
• zooming in and out the map image
• manually moving the map image
• possibility to calibrate the map "on point"
• receive SMS messages with GPS data
• display the point from the above data
• recognize up to 10 friends independently
• recognize changes of friend position automatically
• possibility to automatically: turn the power on, get actual GPS position, send SMS, turn the power off, in the specified period in minutes

Requirements:

• at least one Pocket PC Phone Edition
• at least one GPS Receiver
• at least another one cellular network phone"

A very interesting concept, and I'd love to hear from anyone who tries it on what they think!
