JellyLock is a new tweak available on Cydia and for the moment in beta version (0.0.8-1) which will allow you to unlock your iPhone or iPod Touch like a smartphone with Android OS.
Inspired by the lockscreen interface of JellyBean (Android OS), this rather complete tweak gives you access to shortcuts on your lockscreen.
To get it, search JellyLock from Cydia, install it then perform a respring.
Then go to the native application Settings then Jellylock.
Select the tab Shortcuts app to add shortcut icons for your lock screen (up to 6).
Go to each of the tabs of # 1 to # 6 to select the desired shortcut
You can now return to your springboard and lock your iDevice. Your icons are now available after pressing the padlock.
