Windows Phone 7 : Facebook error 85FB4400

Connecting and synchronizing my Windows Phone 7 - most things are smooth, but not everything.  Here's a few posts quickly listing my issues:

My Facebook seems to have been synchronized, but the synchronization page lists an error.  Users seem to be indicating that this is caused by missing pictures in the contacts.

Anyway, contacts and pictures seems to have been synchronized regardless.  So probably just unpolished software.
