Before now, only Android users were able to take advantage of free turn-by-turn navigation from their phone.

iPhone users, now its your turn.

Through its official blog, MapQuest announced yesterday the inclusion of voice guidance in the latest version of its free iPhone app.

In the post, MapQuest principal product manager Michael Iams describes a trip he took from his Las Vegas hotel to the airport with help from the new application. Basically, users search for the location they are interested in then press the Start button to begin navigation. Whenever you hit a detour or miss a turn along the way, the application brings up a prompt with a button that reads “Reroute me.

Iams also mentions that the app doesn’t waste the phones power, dimming the screen during navigation and allowing the user to customize energy settings.

Other than Google Maps on Android 2.0 phones, the MapQuest app is the only free turn-by-turn navigation app available and the only one for the iPhone, so do check it out.
