Latest FB Beta experience:
1. When scrolling through the news feed, it just kicks out of the app. Upon going back in, it says there was an exception and asks to mail the report (which I did). This has happened to me two or three times now.
2. It doesn't automatically update while you're scrolling (which the released version does). Instead, it just registers that there are new items in the news feed with a little circle and a number to show how many new items are there. This is most excellent.
I've deleted the JDB FB app from my phone for the time being; it seems like the Beta is doing okay. I'm also using the People Hub feed some, too. I may try to delete the app altogether and just go with the People Hub and see how that works. I haven't checked everything, but it seems like there are more functions in the app than in the People Hub.
