Interesting, I received my 810 last Friday and my notes experience is somewhat different.

We run Notes 6, and I use the iNotes6 Template for web access. My action bar works, all my javascript confirmations work, the only thing that doesn't work is the actual list of emails in my inbox, I get icons but no text whatsoever in that message pane. If I double-tap a message it opens in a new window and I can reply/edit etc like normal.

In fact, with the exception of that main screen, it runs more reliably than IE7...
