So what do you do after turning around a company that is now worth $168 billion? What would you want to accomplish after turning the fourth best U.S. wireless carrier (out of four companies) into the fastest growing and most innovative of the major providers. And suppose you accomplished this Herculean feat by flouting all of the usual Harvard B-School conventions. Instead of sporting a short haircut, you grew out your hair to rock star lengths. And in place of an expensive suit, you came to work wearing a magenta colored t-shirt with your company’s logo front and center while donning sneakers.
