I was unable to get my BB calendar events to overwrite ical and was told by Markspace that it was a calendar problem on the 8300. At the suggestion of markspace, I had a new service book sent to my BB which did nothing. After contacting my service provider, they passed me on to RIM who told me that getting the service book resent was an old temporary fix and is no longer a viable solution and that I needed to get a calendar patch which I did through RIM.

Now, when I try to sync, the sync quits and I get the follwing error message:
Starting sync at 7/21/07 9:16 PM...
Plugin Calendar starting
NSInvalidArgumentException: *** -[NSCFDictionary
setObject:forKey:]: attempt to insert nil value
An error occurred while updating the local database from the device.
Plugin Calendar did not complete.

I contacted RIM and they don't support MS so I am now waiting for another slow reply from Markspace. Does this sound familiar to anyone?
