1/ Désinstaller votre version 8.2 d'iTunes de votre ordinateur.
2/ Installer iTunes 8.1.1
3/ Passer votre iPhone (sous 3.1 ou bloqué en restaure) en DFU
4/ Faite un Shift + Click gauche sur Restaurer puis sélectionnez votre ipsw du 3.0
5/ Une fois la restauration terminé vous aurez une erreur 1015 (Pas de panique c'est normal)
6/ Refaite une nouvelle fois un restaure mais cette fois-ci pas en DFU mais en mode rescue ((Affichage du cable USB sur l'écran) Apres l'erreur 1015 votre téléphone se met en mode rescue)
7/ Une fois cette deuxième restauration toujours une erreur 1015
8/ Fermer iTunes (8.1.11)
9/ Ouvrez Quickpwn 3.0 (non Officiel)
10/ Quickpwn va vous indiquez qu'il vous faut reset votre appareil, pour se faire, rester appuyé 15 secondes sur Home + Power. Votre téléphone s'éteint, lâcher tout, appuyer 2 sec sur power et voila votre iphone vous dis que seul un l’appel d’urgence est permis

11/ maintenant itunes va vous dire que cette iphone ne peut être utilisé qu’avec une version 8.2 d’itunes.
12/ Désinstaller itunes 8.1.11 puis installer 8.2
13/ De ma part avec mon iphone autodésimlockable et autounlockable itunes fait tout ce qu’il faut pour que j’ai mon iphone opérationel pour les autres il suffit d’utiliser Redsn0w
PS : Le modem reste toujours en 05.08.01, donc pour le réseau il faut attendre une mise à jour de Yellowsn0w

5 / Once the restoration is completed you'll get an error 1015 (Do not worry this is normal)
6 / Do again a restore but this time not in DFU mode but in the rescue Mode ((Displaying the USB cable on the screen) After the error 1015 phone goes into rescue)
7 / Once this second restoration always an error 1015
8 / Close iTunes (8.1.11)
9 / Open Quickpwn 3.0 (unofficial)
10 / Quickpwn will tell you that you must reset your device, to do so, 15 seconds remain supported on Home + Power. Your phone turns off, release all, press 2 sec on power and now the iphone tell you that only one emergency call is allowed
11 / Now itunes will say that the iphone can only be used with version 8.2 of itunes.
12 / Uninstall 8.1.11 and install itunes 8.2
13 / Use Redsn0w for jailbreak your phone you're done

PS: The modem is always on 05.08.01, so the network must wait for an Yellowsn0w update

Downgrading the FW is not a problem but you will still have the upgraded BB which means UltraSn0w will not work.
