Nike+iPod has only been available on the iPod nano in recent history. The below shown images are purportedly leaked screenshots of the upcoming Nike+iPhone/iPod touch application.
One of the biggest features that we can hope they get right will be the native mapping and location support. This would enable users to not only plan and track routes but richly navigate through locations as well as geo-tag notes for later review. The ability to update your Nike performance specifics on the fly from your phone (to the web) is greatly anticipated as well.
