One last update to Skype is now available for Symbian Belle devices
2.1.23, which was released some months ago, but it was apparently not fully tested. Now fully tested, the app is now available again. It is a voice and chat application only. No video calling is present within the app, though picture, video and other files may be exchanged.
like Symbian, you will not have to hold your breath for further updates of this application, barring a critical business case to do so within a “maintenance” environment.
