Lifehacker have done a very good article on automating your iPhone. The biggest bugbear I have with the iPhone is that I can’t tell it to follow a profile for brightness or access it easily from the multitasking bar. I’d like to be able to use the same settings as I do for Do Not Disturb to turn down the brightness at night.
As soon as an untethered jailbreak for iOS 6.0.1 is available I’ll be setting this up.
