The DM Backup/Restore will backup your contacts, sms/mms, emails, calendars, some device settings, etc. basically almost everything but your third-party applications.
Yes, run desktop manager and use backup/restore. With the backup option it'll back up the entire set of user data from the device (contacts, sms/mms, calendar, bbm contacts, email, etc). Restore will restore everything, and using the advanced option, you have the option to surgically choose what data to backup/restore if you only wish to do certain things, such as the calendar but leave everything else alone...

If you use Outlook, you can sync Memo and Calendar as well as contacts using Desktop Manager (DM). I _THINK_ the calendar can be synced with google and yahoo but am not sure. Otherwise, as noted above, you can backup and restore using DM.
