BlackJack II

We have recently upgraded our phones from BlackJack1 to BlackJack2.
Then we upgraded from Windows Mobile 6 to Windows Mobile 6.1 using the helpful and detailed instructions on Samsung's site.

These worked great with our Exchange 2007.  Activesync magically/automatically made our contacts, calendar, tasks and email show up on our phone just like out Outlook 2007.

We have since retired our Exchange 2007 for Google Hosted Apps.  This requires much more manual activities to keep everything sync.
I miss Exchange 2007 but I don't miss the fear of losing the system due to the difficulties of backing up a Windows 2008 Server.
