The developer writes, here, about v1.01(4):

And coincidently, Shareboard, both Symbian and Harmattan version stopped working soon after due to Twitter SSL enforcing restriction.
The updated bug fixed Harmattan version has been uploaded to openrepos.net, a community maintained repository.
The Symbian version, is available as a standalone sis file from my dropbox.
I will try to keep the app updated and working as long as possible, but no promises since Nokia is dropping support so fast.

Between custom firmware and continued support from developers, it does seem as if Symbian can be viable a little longer!
