My bad ... I decided it felt good enough on my 3G and installed beta 4 on my 3GS a few hours ago. The utility folder did not appear on my 3G restored from it's backup on beta 3, and it did not appear on my 3GS restored from it's backup on 3.1.3.Maybe it's only preinstalled on the 3GS, with the extra icon (compass).
I see GFSarah has the beta on his 3G, not his 3GS. What about you dejo?
You are right..on my wifes 3G the calendar is not for landscape.One thing I've noticed with Beta 4 is that individual calendar events can be viewed in landscape orientation. I don't recall that being possible with earlier betas or OS 3.X, but I could be mistaken ... ? In any case, it makes me wonder if they're working on a landscape calendar view, perhaps even one that will (finally!) have week view.

There's a tiny change to the Photo app in that you can finally view your Photo Roll in a different orientation—unless you have Orientation Lock turned on that is.
