How to remove home-screens on a Vodafone 845? Good day,

after playing around with the Vodafone 845 (Android 2.1) icons positions I ended up with additional empty home-screens (or are they desktops, not sure for the term). What is the proper way to remove those empty screens?
Nicked from here:


  Menu -> Edit. Click the red (-) button in the upper-right corner of the screens you want to delete. Use the [+] button at the bottom to add a new screen.
