I have had a look around Google with no real success. My iPad is stuck on full brightness, it is brighter than the sun and eats the battery like a fat kid eats cake. None of the sliders do anything; It's jailbroken on 4.2 I believe and I really want to avoid doing a restore because it's a mission to get everything back the way it was with all my apps, books, videos, Cydia apps and so on. Anyone else heard of this? Cheers!
