I actually have had a cell phone cause an issue on a flight. Up front we wear headsets and much like the radio in your car they can occasionally pick up a loud clipping sound from the cell phone. It tends to happen when the phone is sending/receiving (calls or texts) or when it is searching for a tower.

Let me tell you if you think it's irritating in the car try it with the speaker half an inch from your ear. I have actually asked passengers in flight to check their cell phones because the noise was interfering with our communication. Other than that, no cell phones don't cause the wings to fall off. No I don't want to sit next to someone on their phone telling a buddy all about their last colonoscopy.
