Old events (like a week ago) are not deleted, sometimes events are not transferred, items deleted on the phone get recreated. It's a real mess. Surely I must not be the only person who is having these problems? There were always problems at the DST boundary, these may be related to that, but under 5.1 things are much, much worse. I already gave up on the notes because the sync process was replacing updated notes with old versions. Where it got the old versions I wasn't sure, because it happened whether I updated them on the PC or on the phone. Nobody else had ever heard of this happening... I remember the iPhone sync was reliable when I was using iCal on the Mac. Now I no longer have a Mac which syncs (since PPC Tiger is not supported), I have to use Outlook 2003, and it's so bad I'm thinking of giving it up and getting (shudder) a Windows Phone. I need the organizer to be usable; I have about 200 calendar items.
