Ok I went to this site

http://mike.saunby.googlepages.com/x11vncfornokia7702

and followed the installation instructions but i don't know what this means.

HOW TO INSTALL

Save the file _armel.deb to memory card. Then using Application Installer in Control panel install the package. To install on the N800 or N810 'red pill' mode is required.

What is red pill? I installed x11vnc and it shows up in my Extras folder but when I click on it absolutely nothing happens. Anyone care to help?
