The rumors are literally running around Europe that Samsung will make an Adidas branded phone with a heart-rate monitor that is linked to the phones' music application. The phone is supposed to be loaded with a calorie counter,pedometer and a virtual personal trainer to keep you in tip top shape.
Other major brands likeand have developed customized phones so it may make sense for Adidas, especially as Samsung is also an official sponsor of the next Olympic Games. Nike already has a connection with the Apple and the iPod, so who knows, maybe we will see a Nike branded iPhone in the future.
Only problem is the rumors are in Europe which means we may never see this little piece of tech in the USA.
