I recently downloaded OS4 for my iphone 3G. I use entourage 2008 a great deal and have had no problem syncing my contacts and calendar until OS4. After download OS4 I can no longer sync my contacts and calendar. If I schedule an appointment on my iphone and sync the appointment will not appear on my phone. Contacts will not sync either. I used the sync services in entourage 08 and it still won't work. Any ideas? I'm at a loss.
