Still not quite sure about all the details of what's changed, but one thing that caught my attention... anyone else notice that the Internet Call dialpad has been re-arranged? It's now got an area where you can use the keyboard (on your N810, or drive yourself batty with the vkb popping up on the N800) to type in the phone number instead of just using the giant dialpad buttons, and has turned into a drop down that will let you choose phone numbers that you dialed previously (not from your contacts, but recent numbers). I could be wrong, but I don't recall that being there before... the button positions have definitely moved though.
