FREE: Nike + iPod Sensor

The listing, Nike + iPod Sensor has ended.

BRAND NEW, never used, still in unbroken packaging.

Description from Apple's website:
This wireless sensor works with your iPod nano*, iPod touch (2nd generation or later), iPhone 3GS or later, to track your workouts. Insert it into the built-in pocket beneath the insole of your Nike+ shoe and pair it with your existing Nike + iPod receiver attached to your iPod nano.
iPod touch (2nd generation or later), iPhone 3GS or later, include Nike+ support built in. So you can get all the benefits of the Nike + iPod Sport Kit without the extra receiver.
This sensor is also perfect as a replacement for a sensor that has been lost or has exhausted its battery. Or it's great if you want to have a sensor for a second pair of Nike+ shoes.
Please note: This package includes only the Nike + iPod wireless sensor. If you also need the wireless receiver for iPod nano, purchase the complete Nike + iPod Sport Kit.
