Midmarket: 10 iPhone Navigation Apps for Your Next Driving Adventure

Sometimes you need a little help getting from points A to B, something a number of developers realized when they began designing navigation apps for the iPhone. Many of these apps take advantage of the GPS chipset embedded in the iPhone 3G and the iPhone 3G S, which allows for turn-by-turn directions and easy viewing of local points of interest. Other apps, including Google Earth, focus primarily on actual maps as opposed to step-by-step directions. Many of these apps attempt to justify their high costs with that GPS integration and high-quality renderings, as well as a host of secondary features such as lane assistant. For those who don't want to spend quite so much on apps, or don't need that many gee-whiz features, a few of these options are notably cheaper.
