Same problem. In the previous version I managed to sync my contacts and memos. Calendar absolutely refused to sync. Now I can run my apps without a problem but can't sync any of my data. Very frustrating as now most of what didn't work now is running and viceversa.

Is there a way to transfer the .pdb files of Contacts/memos/to dos/calendar directly to avoid having to hotsync? Has anyone tried this.

I'm about to give it another try right now.
