We thought he probably would've at least stuck around long enough to see the Tube get announced later this week
, but Nokia CTO Bob Iannucci has announced that he's stepping down from the world's number one cellphone maker effective immediately for undisclosed "personal reasons." Though it might seem that the move leaves a gaping hole in Espoo's senior leadership, the company actually says that Bob will continue on in an advisory role while it decides whether it even needs a CTO going forward. Bob also served as head of the Nokia Research Centre -- also known as the place where you get to play with Haptikos
-- where Henry Tirri, current head of the center's Systems Research group, will be taking over.
