The good doctor, Sherif Hashim, found a new iOS 7.1.1 bug that grants full access to the contact list while the phone is locked. iOS 7.1.1 passcode lock bypass with full access to the contacts list, very easy, and with additional single manipulation (i m not showing that) you can access all the contacts details, edit/copy/share/message/email them, anyway, keep secure and disable Siri on lock screen till the next iOS update

FSM EXCLUSIVE DEAL PS: I couldn’t replicate the method demonstrated by Sherif on an iPhone 5s running iOS 7.0.4
