The one thing that I have found that annoys me in iOS6 is that when I unlock the phone, it seems to take ages for the brightness to reach the level I specified in Preferences. Instead, it seems like Apple are ramping up the brightness slowly (OK it takes probably less than a second) I use my iPhone as a make-shift flashlight on occasion and for this purpose it was better when the full brightness came on immediately.
I kinda wish Apple would put a flashlight toggle on the home screen (like the camera toggle).
