With the addition of Atom, the lock bar replacement, now available in Cydia ($1.99), and SubtleLock the two make for a great minimal lockscreen. Atom allows for a set of six different apps to open from the lockscreen. As of the current version you have to set 6 apps no more nor any less. Nonetheless this is useful if you have six apps you need quick access to without the arduous task of sliding an unlock bar, finding the icon and tapping on it. Go get it now!
