Hello, I've read other threads with similar problems (most of them for WP7 though) about missing or late twitter updates. I noticed something else, even though updates both in People Hub and Groups are fine it's the contact thumbnails that are outdated. On previous phone L800 it took a day or two to update, but here it's plain stuck. Spent a couple minutes on-line too, found no mention of this specific problem. It's not a biggie of course, just wanted to let it out. Anyone experiencing the same?

On Lumia 920 pre-Portico, Vodafone DE branded
- twitter contacts only (not linked to anything else)
- manual sync doesn't do it
- opening the contact's card won't do it
