Narrative:

First officer was flying masty 2 arrival with #2 autoplt engaged. Aircraft started a turn to intercept the 341 degree radial to cowboy VOR. Turn looked a little early, then realized was about 3 mi early. Switched displays to raw data to properly intercept. Then #2 autoplt self disconnected along with #2 autothrottle -- no autoland, no airspeed, no windshear, and #2 FCC fault. Had flight attendants make an announcement to passenger concerning use of electronic devices with a walk through of cabin. Tried to reinstate faulted equipment with limited results. Landed without further incident. Was within airway limits at all times. Flight attendant informed me on ground that a passenger did in fact have a cell phone/pager that was on -- even after being warned. Subsequent interview of passenger was told he had it turned off. With the possibility of him telling the truth and having a #2 FCC failure, I released the passenger after a brief lecture. Callback conversation with reporter revealed the following information: reporter had no feedback from maintenance about what the failures were in the aircraft systems. He felt that the removal of electronic devices would probably correct the problem. The devices in question were a cell phone and a two-way pager. The passenger was sitting in first class above the area of the electronics bay. Other passenger reported that the units were put away, but not turned off.
