Sorry to say but it is not possible. I have tried. When I export it, I get a svc homescreen error. The only way I know how to is to replace the icons with 'blank' icons but the problem with that is on the icon (application) screen, those icons you replaced with blank icons on the homescreen will also be blank on the icon screen. Hope I explained it clearly...
If I am wrong (I am sure someone here will tell me I am...lol), please share with us how to do it...
