About synchronization conflicts
A synchronization conflict occurs when you change the same email or organizer data item on your BlackBerry® device and in
the email application on your computer.
If you reconcile your email using wireless email reconciliation, on your device, you can set whether the email on your device or
the email on your computer takes precedence when an email reconciliation conflict occurs.

If you synchronize your organizer data using wireless data synchronization, the organizer data on your computer takes
precedence over the organizer data on your device when a data synchronization conflict occurs.
Research In Motion recommends that you regularly create and save a backup file on your computer, especially before you
update any software. Maintaining a current backup file on your computer might allow you to recover device data if your device
is lost, stolen, or corrupted by an unforeseen issue.
