and here's what vaulted to the top of our "instant index" tonight. Is it possible she is back? Help me obi wan kinobi. The answer is yes. Carrie fisher will return in her role of princess leia. All we want is to watch princess leia one more time. The first new film, due out in 2015. And would an iphone by any other name have been as cool? We learned today the device nearly had to be called something else because a competitor had a trademark on the name iphone. When steve jobs and his team drew up a list of alternatives, the number one name was mobi, short for mobile. Eventually they cut a deal and the iphone, thank heavens, was born. And a familiar face with some difficult news tonight. Valerie harper, who brought rhoda morganstern to life. She went public today with a deeply personal battle. She has been diagnosed with brain cancer, a rare form. She says doctors have given her three months. And today, the outpouring was overwhelming. One fan, with this poignant message. "The reason we are all so sad is because we are all rhoda." She is facing it with steely grace, saying what she thinks about is being here now. And a world of tv-viewing friends send her love tonight. And as always, if you see something that gets your attention for our "instant index," please tweet it to me zblvrjts dianesawyer.
