xGPS Util is a small free utility to be used with any xGPS Module sold through this store. This utility allows the user to get his position and speed, and to do any firmware upgrade of their xGPS Module when they are available.
This software does not display any map or your position onto a map. The software called "xGPS" (which, when available, can be found here) can display your position onto a map..
The software is available through Cydia on jailbroken iPhone 2G or iPod Touch running firmware 1.1.4 or 2.0 or greater. The iPhone 3G is not officially supported but it works too.
A "quick start" guide showing how to install this software on your device is available here: Quick-start Guide for xGPS Util
