I have a Blackberry 8310 running V4.5.0.110 with major calendar issues. I run two email addresses on my blackberry, one is a hotmail address and one is a campus email address. The calendar I use is in outlook but not associated with either email address.
However when I sync my blackberry and then look at my calendar it list my events twice on my calendar and also brings up a hotmail version of the calendar and a campus calendar.
I have tried going to device default to set my default calendar to device default however when I do that device default is not a option the only option is for the hotmail calendar and the campus calendar.
