QuickSpring will allow you to quickly respring and from Springboard itself, most of us do it with SBSettings, but there is someone who needs something faster or who does not have SBSettings installed.
You can download it for free from Cydia.
You need to have the jailbreak done.
Anja and how it works I have downloaded it and it does not appear nice where I give it for the respring and something else please try to give the clearest explanation bro.
