Mine warned me about the update but I postponed it a couple times until I could learn more about the update. I let the updater do its thing yesterday and after the multiple reboots which are expected, everything on the phone continue to work well. I didn't notice any changes at all.
When I read one of the responses above say that the 'global' network was selected, I checked mine and found the same thing.
I thought global had to be requested to be added as a feature on a person's plan. What would happen if we just leave it set? I haven't noticed any battery drain since the update, so I'm thinking about leaving it set.
The NFC icon doesn't show up on my phone anywhere. For those of you who see it - where does the icon appear?
