Backup and Restore are part of the BlackBerry Desktop Manager software package. It comes on a CD with each new BlackBerry, or you can download it directly from BlackBerry Support.
Backup your current device, restore to your new device.
If you have third party applications installed, there is a seperate Switch Device wizard that does the transfer and correctly updates all of your BlackBerry Messenger contacts.
so we're talking about all of your contacts? not kust your bb messenger ones? i have a curve and im waiting on my storm to get here and was wondering the same thing.
