If you have Nike + iPod workouts stored on your iPod nano, iPod touch (2nd generation), or iPhone 3G S, you may want to upload this workout data to nikeplus.com before restoring the device. Restoring your iPod or iPhone permanently removes all workout data stored on the device.* * nikeplus.com maintains a record of your previously uploaded workouts. Restoring your iPod nano, iPod touch (2nd generation) or iPhone 3G S does not erase any previously uploaded workouts on nikeplus.com.
