Narrative:

Line up check was completed. The 'takeoff configuration ok' advisory message was confirmed. Takeoff clearance was received and the takeoff roll began. At around 60 KTS a takeoff configuration warning was received. The takeoff was aborted. Tower and flight attendants were advised. Upon clearing the runway the first officer advised me that his cell phone had been inadvertently left on the center console between the thrust levers and the flap selector. As the takeoff was initiated; the phone slid off the console. The improperly stowed phone struck; and then rested on; the rudder trim switch; causing rudder deflection. The rudder deflection caused the configuration warning. After a brake cooling time was observed and checklists completed a second uneventful takeoff was initiated.
