I've been syncing events w/attachments to my Pearl fine...the attachments are dropped and just listed as a file name in the Notes section of the event, but the events themselves do sync.
Maybe an update provided w/BB OS 4.3? I'm on DM 4.2 SP2.
I've always resolved any sync problems by deleting the calendar databases from the Pearl and syncing again...works for me as I create the majority of my appointments in Outlook, so I am rarely in a sitiation where I'm going to lose any data by doing that.
