(CNN) -- As of February, more U.S. adults own smartphones than simpler feature phones, according to new research from the Pew Internet and American Life Project. Well, to be more specific: In answering questions from Pew, 45% of cell phone owners said that their phone is a smartphone. Also, 49% of cell phone owners said that their phone operates on a smartphone platform common to the U.S. -- which includes BlackBerry. According to Pew: "Taken together, just over half of cell owners (53%) said yes to one or both of these questions." Here's how it breaks down, by platform: 20% of U.S. cell phone owners currently have an Android phone. For iPhone, 19%. BlackBerry, 6% (a 10% drop since as recently as May 2011).
