I'm an IT server and network administrator, and I know how upgrades go.... 50/50 balance between smooth transition and a disaster... Good luck Roland, we're all counting on you.
Maybe every time I post pictures from my iPhone post upgrade, they won't be upside down? I know my pictures are right side up when I take them and view them. I've started opening the pictures on my computer and re-saving them before I post to make sure they're right side up.
