Hi, I wish to express a future idea in addition to the iphone, I have two boys who play a lot of sports for the school & for a private club, we all possess an iphone but getting in touch with the lads is almost impossible, because they have to put their phone in a bag or in their trouser pocket. Can we design a watch /bangle device that you can wear whilst playing sports so you can be contactable , flash messages or even can detect where you are because they also visit the local parks with friends, i'm sure this would be easy to create & would be purchased by most parents who need to know where there children are at all times, please update me, I know I am desperate for a devices like this, Thanks, Nathalie
