EffacePad is a tweak available since last night in Cydia for our iPhone, iPad and iPod Touches, it is thought to improve the design of the screen for entering a security code.
In the attached image you can see the change that EffacePad makes for us after installation and we are talking about moving the button for making emergency calls and the one for canceling the code entry, so we are not talking about any major change that is offered to us.
EffacePad cleans up the lockscreen passcode screen by moving the cancel/delete button and the emergency button into the keypad. Configure options from Settings.
EffacePad is available for free download from Cydia's BigBoss repo.
