An article in American magazine InStyle's October issue features comments by stars of stage and screen on how much they like the tune their phone plays when someone calls them.

The magazine says that Rachel Bilson, known best as Summer Roberts in hit American show the OC, has a different ringtone for every number on her phone!

The choice of movie theme ringtone is a popular one for many Americans, with research showing 2.5 million of them were downloaded in August.

The same investigation by American company M:Metrics revealed that over 20 million Americans downloaded ringtones during this time.
