Running with Nike + iPod and iPhone 3GS

Apple quietly released iPhone 3GS support for the Nike + iPod workout tracking system for runners, walkers, and people who like to work out.

The iPhone 3GS, like the second generation iPod Touch, includes built-in Nike + iPod support to monitor your workouts. Runners can purchase the Nike + iPod Sensor for $19 and slip it into either a Nike+ compatible shoe or any shoe (using one of the below hacks). The iPhone 3GS is thus capable of tracking distance, calories, pace, and workout duration during a run. The iPhone 3GS has a built-in receiver that eliminates the need to plug in the receiver sold with the Nike + iPod Sport Kit.

Using the Nike + iPod app

The Nike + iPod app is easy to use after you link it to your iPhone 3GS. You simply go to Settings, choose Nike + iPod, and turn Nike + iPod on. When Nike + iPod is turned on, its icon appears in Springboard (iPhone desktop). The app provides audible feedback on your speed, distance, time elapsed, and calories burned during a running (or walking) workout.

Note:If you have more than 176 apps installed--passing the display limit of Springboard--and you are running iPhone OS 3.0, you'll have to use Spotlight to launch the Nike+ app.

What do you think about this new iPhone 3GS feature? Are you concerned that the iPhone 3GS might be susceptible to sweat damage during a workout like it's predecessor, the iPhone 3G, was? Is shoe hacking ethical or does it lead to a life of crime on the run?
