Normally I will use "Page Read" and it will mark the first 20 read, then show me the next 17. However, now it will jump me back to the main page (like it is out of items) and show me the unread count (17) but when I click on it, the feed shows up empty, and if I refresh the feed listing page, it doesn't show up anymore.

I don't know if this is a change in the web UI that caused a bug, or if it's the new iPhone OS 3.0 (I have a 3GS, so I got 3.0 preloaded too) - perhaps the newer Safari and the web UI have a minor incompatibility?

It should be easily reproducable. Just get a feed with > 20 items, mark only the specific page as read, and it should make the entire feed read (technically, but it won't appear to have until you refresh the page and it's gone)

I still prefer the web UI over the iPhone app. It's so clean and easy. I just wish you could access your clippings from it! Thanks a ton for your great service.
