I don't have a recent iphone yet, but want to know if siri and voice dialling can be disabled without having to set a password if you do following steps in the latest IOS 8 beta: 1. Turn Siri on --> settings --> general --> Siri 2. (just for the case you deactivated Siri here, not sure if you need to do that) settings --> general --> restrictions --> Siri on 3. settings --> passcode --> Turn Passcode on --> Allow Access when Locked --> Siri OFF 4. turn passcode OFF again Especially if at the end you turn passcode OFF again (step 4), will it still have both siri and voice dialling disabled or not from lock screen? Is step 2 required? Could somebody please try out the above steps and let me know if it works or not. Thanks alot!
