mám iPhone s fw. 3.1.3 blokovaný na AT&T.
Skúšal som asi všetky možné návody a spôsoby(redsnow, custom firmware&iRED, blackra1n, spirite) na unlock a jb - ani jeden nefungoval.
Blackra1n vypíše okno ako keby bolo všetko v poriadku, ale iPhone (asi) skončí v DFU a a z tade sa nehne.

Na iPhone čierna obrazovka a v iTunes(9.0) sa dá dať iba restore.
blackra1n log:

Pokiaľ v redsn0w vyberiem ipsw súbor, vypíše

Všade sa vyskytne nejaká chyba

Prosím o radu.
Ďakujem
