For the people who are new i’ll briefly explain. xGps is the navigation software that works together with the xGps module that has been released for the iPhone 2G. Check my old post regarding this here.
xGps promised to release navigation sofware that works together with their module. Today they’ve released both applications. xGps and xGps util. The xGps application supports 2 maps (Google and Open Street map). The way the app works is by selecting a area on the map and then the map get’s downloaded onto your iPhone for later offline viewing. For now it’s not yet possible to plan a route but later versions do promise that functionality.
xGps util 1.0.0-1 is a application that will display Longtitude, Altitude, 
latitude and several other handy GPS data.
The full manual for xGps util can be downloaded here.
To download both app’s you will have to add a source in Cydia. Add the repo http://cydia.xwaves.net.
Note: The xGPS software is only compatible on firmware 2.0 and greater (2.0.1 and 2.02 etc…) and works only with xGPS Modules (you can also use it without a GPS).
