The world has gone iPhone crazy since Apple released v2.0 of its sleek mobile device, and while GPS and 3G have been big draws, the multitude of available software apps in the new App Store has been the real wild card. One app that has us really psyched is a new automotive performance meter called Dynolicious from BunsenTech. It uses the accelerometer inside the iPhone to let you record 0-10 through 0-100 times, quarter mile and trap speed, Lateral Gs, horsepower and more. Results are also displayed in real-time on the phone itself with graphs and a speedometer. You can also configure the tool with updates to your car, weight, before and after performance measurements, and keep a complete history of all your runs.

Yes, we were among the suckers who endured the idiotic lines, activation woes and intermittent service that you've undoubtedly read about after the iPhone 3G's launch this past Friday. But our reason for suffering through myriad hassles to get our hands on Apple's newest hotness wasn't purely selfish. We wanted to see whether the iPhone 3G's new GPS functionality was worth the cost of admission or if we'd be better off buying one of the many stand-alone navigation units currently on the market. Make the jump to find out if it's worth your hard-earned cash and a place on your dash.
