Kinda cool actually. But, oddly, my ipad got the carrier update, but doesn't have the notification options available.
me too now i can FT over cellular. I'm NYC using an Iphone 5 and I have the grandfathered unlimited plan also. but i didnt get carrier update 14.5 all i got was 14.1 .Besides the government and amber alerts, I can now use FaceTime over cellular. I have the grandfathered unlimited plan so I'm happy about it. If it matters any I'm in Houston using an iPhone 5.
I just got it too a few hours ago.
No idea if there's any changes.
Here you go; a diff of the previous one that I had and 14.1: http://paste.debian.net/hidden/198ed7c1/Someone who's jailbroken needs to do a diff on the new and the old files....
