"VOICE DIAL ONLY

With the advent of Siri on more and more devices, it seems weird that Apple would update something that is as old as the iPhone 3GS, but if you still use Voice Control, there is a new section in the settings for it that allow you to set it to ‘Voice Dial Only’. You can choose a language from the list to use Voice Dial with."
 
Haven't noticed anything yet.

*Edit* - My weather in the notification center was extremely buggy, now is very quick and smooth.
 
Surprised they aren't getting a reworked music app pushed through this release to match the interface of itunes 11 and remote app
