Jailbroken iPhone owners will be pleased to know that xGPS has launched and is now available in Cydia. It takes driving directions from Google Maps, adds real-time audio for turn notification and in case you’re afraid your iPhone might lose a signal (thanks AT&T) you can download the entire map/route ahead of time for piece of mind.

The guy in the video is actually using xGPS on his 1st-Gen iPhone and you can get it on your iPod Touch as well with the right external GPS unit.
