The man today at the Nike Factory store told me I didnt need the actual sensor for my shoe if I have the app on my iphone 4. So I didnt get it, and came home and tried to get it to work (with no sensor) and typically enough, it didnt work. So How is this phone supposed to recognize a shoe with no chip?!?! And if it is a case of the device is the only thing tracking everything, than why cant i run in KSwiss or Adidas? Please help before I spend money that I may not have needed to.

I want to know if the new Nano will find the Nike + shoe sensor or does it just rely on the bouncing to try to estimate distance of a workout? I like using my old Nano for runs cause it's VERY light, and very accurate at recording my run and giving me feedback about distance and pace. But it needs the Nike plug to find the sensor.... did they finally build that chip into the nano? or are they just saying the software that works like a pedometer is good enough for most people?

I am not planning on running down the street with the iPad in a giant arm band. But What if running on a treadmill, I could use it to track my run and watch videos on the large display. Even if you have to use the receiver like on the nano. I doubt this will work but just curies.
