    The point is that in step 8, when I come back to Cydia, The "Restart Springboard" sign doesn´t appear. I´ve tried many, many times, but always unsuccessfully.

      dont worry, before doing anything have SBSettings installed whereby you can hover your finger on top of iphone screen and still do a Re-Spring

    Bonjour , Moi j'ai réussi à débloquer un de mes iphones 4 en suivant ce tuto mais j'arrive plus à le refaire sur les autres iphones 4 de mes amis.

    • Jugurtha Hadjar says:

      Bonsoir, Willy

      Cette méthode ne marche plus. Je crois (selon un connaisseur) qu'elle n'a fonctionné que pendant trois jours.

      (This method doesn't work anymore, it worked for maybe three days and that's it.)
