@matigo Thanks. Nice job. But will the unpin button show on 4S-sized screens? ;-)
When you’re accessing from the 'save to homescreen' webapp, rather than the full browser app, you need to delete and recreate it. Just swiping up and away didn’t seem to flush it out fully. In fact, when I went back after that it even remembered that I’d tapped on a pinned post and had the pins showing. And there’s no reload option. It’s not difficult to remake the home screen icon though.
