Those at 7.x waiting for JB, maybe treat 7.0.4 as exercise in restraint. Won’t affect JB if you slip up, but test your ability to avoid it!

Apple releases iOS 7.0.4 for iOS devices earlier today. The minor updates brings improvements and bug fixes, fixing a bug that could cause FaceTime calls to fail. MuscleNerd confirmed that updating is safe for jailbreakers BUT only if you’re already on iOS 7. Updating to iOS 7 will result in loosing your ability to jailbreak, and there’s no ETA for an iOS 7 jailbreak.
FSM EXCLUSIVE DEAL …but for those enjoying the 6.x JB, avoid 7.0.4 . There’s no going back (always worth saying that for sake of JB newbies)
