Hello everyone. I have a jailbroken ip4 that's been running fine on firmware 4.2.1. This morning, when I tried upgrading/restoring to 4.3.1 in anticipation of applying the new jailbreak (this via Redsn0w on Win7, by the way, though I also have a Macbook Pro), I got the Error 3194 -- which I gather has to do with Apple not recognizing an unsigned ipsw, or something to that effect. iTunes and all software is up to date. Can someone walk me through the necessary steps to resolve this issue? I've done a couple of forum searches, but remain a bit confused. This has nothing to do with locking/unlocking baseband. All I want to do is to install Apple 4.3.1. on my jailbroken 4.2.1. Many thanks in advance (and regards from New Orleans)...A.
