You can download desktop manager for free from Blackberry.com web site.
If you are able to get this to work, good luck, because I am unable to get the desktop manager to find the blackberry, nor is the USB port reading what the device is.
But you can give the desktop manager a try,and also download the software for your blackberry. I'd suggest you download the 4.3 version of the software and be sure it is in the language that you speak (they have several, look for ENG for english)
