Figures on accidents involving cyclists where motorists are using cell/mobile phones
As Batman has commented, I suspect getting the data down to this level is probably going to be quite hard.  That said there is some Australian research which may be of interest to you.  In particular a study undertaken in South Australia which looked at the circumstances surrounding crash involvement for a group of 61 bicycle riders involved in a collision with a motorised vehicle who were admitted to the Royal Adelaide Hospital over the period between January 1 2008 and December 31 2010. You can read a summary of this study on my site. 

This descriptive study provides some insight into cyclists and motor vehicle interaction and adds to growing literature on the subject.
