Ok, I don't want to click the link but obviously this is a marketing ploy for the company. Of course, I think they can find a lot of people willing to take the challenge because of the attractive prize.
But I guess, they will just choose one person only for this challenge and will follow the progress like how is he/she doing without his smartphone or if he/she can really maintain the agonising year without your phone around. We all know that every corner of the world, you can find someone with at least one smart phones, so this is going to be interesting.
