I've just upgraded my 1.1.2 unlocked phone to the 1.1.4 with iPlus 1.2.
I just wanted to say that it was an extremely easy and even though I was quite scared how it's gonna turn out, it went flawless. My iPhone is now on 1.1.4 unlocked, with every function working like a swiss watch.
I just wanted to post this so people who are sceptical about this method may have it easier to decide.
Just follow the http://www.hackthatphone.com/114/iph...k_windows.html tutorial (this one is for Win users).
During my process of unlocking I had to restore it to 1.1.4 two times (just as it is mentioned in tutorial). The second time it went through without any mistakes. It took me about 20 minutes to complete the whole process.
Well, that's about it...
Take care and have fun unlocking.
