Nokia has launched a new teaser website, Somebody Else’s Phone, to announce a mystery product on the October 13th. Not much is revealed on the site except for a countdown timer running on the already launched 7610 Supernova slider and a trailer featuring three people who have fed almost all of their lives into their cell phones. The “Somebody Else’s Phone” campaign could point to a device or a new service just as well, but the use of a device that is already available might turn our bets to some kind of a service rather than a new handset. With just 2 days to go, we won’t have to wait long before we know and we’ll keep you in the loop as it emerges.
