Unluckily for me… the synchronization of contacts and calendar items is strange. The items are usually synchronized, but iSync reports bugs and errors during the whole process.
I was looking over the Internet for the resolution, but I did not find any. But as I know, it takes several days to Google to provide a good and quality data.
Or do you have any solution to make iSync not to report fails during the synchronization of Motorola KRZR with Mac OS X?
