I have a new D2G that I just got. I had an original Droid before that. I have the corporate sync set up and it is syncing my email and calendar. It did sync my contacts originally but when I recently added a new contact to my Outlook address book, my phone never got it. I waited over 24 hours and finally had to disable the contacts sync in Settings > Accounts > Corporate Sync and then reenable it. How do I get it to sync the changes without doing this?
