I have an iphone 4s with ios 5.0.1 with jailbrake. I´m trying to upgrade to ios 6.1.1, but i can´t. I don´t have the shsh file for my iphone. I´ve tryed with redsnow (but as i don´t have de shsh, it didn´t work), changing the itunes server (got error 3194, 21, 1600) and i didn´t find any place to download the shsh file. Could someone help me???
