I have traveled with two cellphones on more than a 100 trips since we have had a side business for years. A few trips I have traveled with two laptops (demo unit for a presentation). I was asked why I had 2 cell phones on one trip at DFW airport. Sure it was a one time question but you never know the real purpose of the question when the TSA agent who looked early 20's used the word "suspicious". You should always be prepared from the unexpected from a TSA agent.
