It was definitely quickly glossed over in today's iPhone activation and sync walkthrough, but Apple pretty clearly stated that Mac users with Entourage can sync their calendars with the iPhone through iTunes, and PC users can sync their Outlook calendars the same way. That's totally heartening for any corporate calendar users wondering how they were going to get their datebooks on their new phone, but there was no mention whatsoever of contact syncing via Outlook / Entourage for Active Directory, just Apple Address Book and Yahoo Address Book (which could potentially leave PC users in the lurch). So, your thoughts?
Update: According to Mossberg's early review it does in fact sync contacts too! Not the same as live, over the air AD access like on WinMo, but definitely close enough!
