I've just installed iOS6
It's good
I like there is now a mode called do not disturb lol under settings
It's been floating around for a few days already.
If anything like last time a big update came out was anything to go by its worth doing it early or late because last time while world tried to update at same time and it overloaded apples servers.. Was taking like 6 hours to download and when it came to install it was showing errors because iTunes couldn't communicate with apple servers.
Nightmare
