An exercise I did with nCloth on the suggestion of my TA who is a technical director. I modeled and rigged the phone, so the buttons can be keyed if a character was to interact with them. To make the chord I created a cv curve and then extruded a nurbs circle along and around the curve to get the spiral chord. I then created an nCloth object from a high res plane that I put inside the chord. I adjusted the collisions on the nCloth so it surrounded the phone chord and then hid the nCloth. I then made this nCloth drive the movement of the spiraled phone chord.
