Turn-By-Turn Voice Navigation Comes to Jailbroken iPhones

Six months after the App Store was launched, the iPhone app gray market lives on: turn-by-turn navigation has come to jailbroken iPhones in the form of xGPS.

xGPS uses Google's map data and driving directions, adding a real-time navigation readout and a voice engine. You can also select a map area to download ahead of time, just in case you expect to lose your data connection during the drive. As you can see in ModMyi's video above, the app also supports a number of external GPS units, so 1st-gen iPhone and iPod Touch users can get in on the monotone fun too.
