Although Wikiwide is totally correct in his reply, I'd have to argue in the context of this thread this is still up for debate. As I pointed out already before Skypes own techsupport pages list Symbian and WP7 as the Legacy operating systems to be axed, and there is no mention of discontinuation of support for Nokia N-series phones (Maemo5, 4, ...)

I'm not pointing this out just for arguments sake, but because I'd like to know if anyone has any other information about this. For example I received email from Skype that my desktop client was too old and the support for it was to be axed, so they definitely know which version I'm using, but I havent received any mail from Skype that my mobile client is outdated. Has anyone received mail about their N900, Symbian or WP7 clients?
