OK, I have done some tests. You can't change the "hidden" checkbox of the "home" folder on your Blackberry. You have to do the following:

• Connect your Blackberry to your computer
• Don't start Desktop Manager on the computer
• You should now see a drive appearing in the Explorer on your computer
• On this drive, navigate to the home folder, right-click and choose Properties
• Un-tick the "Hidden" check box on your computer
