If you haven’t heard, the iPhone now supports turn by turn navigation apps. These apps essentially turn your iPhone into one of those portable navigational devices which people refer to as “my navi” or “my GPS”. Overall, the apps are quite good. They work well, they look great, and having a turn by turn navigational system on your cell phone is highly convenient.

iSmashPhone have written a small article comparing 5 of the most popular turn-by-turn navigation apps for the iPhone. They even created a lush table summarizing the points of each app. Check it out here.
