Earlier today, Apple quietly pushed iOS 7.0.3 to all compatible devices ( read more about it here ). At the time it was uncertain if it’s safe to update, but MuscleNerd announced via Twitter that the new iOS won’t impact the jailbreak at all. You can update.
NOTE: ONLY update if you’re on iOS 7 already. If you’re running iOS 6.x and jailbroken, DO NOT update. There is no jailbreak for iOS 7 yet.
