I have just got my BlackBerry Curve 8520 as I thought it could synch with ICal through the Blackberry desktop software (of course I am utilizing a Mac). I have handled to synch contacts and notes but in the calendar field it simply says "there are no writable calendars available for synching on this PC." I have checked all the applicable boxes in all applications (I previously utilize MobileMe and synch other devices). Does anybody have any idea how I get it to work? There is a variety of post but not any seems to have had the similar difficulty.
