Keep waiting. Nokia won't be giving you any answers because Skype is not developed by them, much in the same way that Microsoft support will probably have a good laugh about the naivety of the question before politely referring you to Skype.

Your (and our) best bet is to hope that Skype introduces support for the built-in video camera for OS2008. In the meantime, video calling works fine between N800/N810s using the built-in client, though I have had limited success with Gizmo.
